19000 miles yesterday and blammo, all of a sudden - issues.

If anyone has input or ideas it would be helpful.

Car setup is in profile if you want to check it, - basically s2 w/toys, intake, lfs throttle body, 3" catless dp, borla...I am currently running 94 octane sunoco with NOS racing octane booster(for HOM use)

Problems:
1) Clicking in left front wheel area under inital acceleration.
-upon inspection the boot (i think it's CV) next to the abs hub at the end of the axle
is covered in grease and splattering it everywhere.

2) When I let off the gas, the rpms hold around 1600, gradually build up to 2200 and then
gradually fall back to 7-800 where they should be.

On question 1, it sounds like a blown cv joint, right? Just curious, I will be having the dealer address this one as soon as I can get the car in.

Question 2 is my bigger concern, since that one is probably related more to my mods, and I feel I should address it. Is this a tps issue? Or a tip sensor issue? I am not too sure, and I would love if someone could shed some light for me. What do you think I should do?

I have been having the hard start issues, recently, and heard that I should maybe clean the throttle body, but thought mine should be fine (maybe I was wrong?), since I replaced it with the lfs only a couple of months ago.

I wouldn't think it is related, but I put a can of NOS octane booster (60 point version with the black label) in for the first time and have been using HOM with it. This couldn't cause the "sticky" revving, could it?

Thanks guys/gals

 

Problem 1, check the ball joints. I had a click/clunk when I turned the wheel to the left or right and accelerated (speed regardless), my ball joints had cracked and were leaking grease everywhere. Dealership fix.

Second problem, does in fact sound like a TPS issue, or a stuck Throttle cable. The TPS is a TSB, so its easy to get that replaced even if it isnt the problem. If your warranty is voided check MoparSuperCenter.com and grab the TPS-fix wire for around 17.26, very easy to do, its just a swap.

Thats what it sounds like to me, I could be wrong, Im basing it on issues I've seen/had with my car and a couple other cars (one with a sticky throttle cable, and one with a broken TPS (that got so bad the car refused to start). Best bet: call your dealer and have them check it out. My dealer rocks so I have everything done and installed there, hopefully your as lucky, but again the TPS shouldn't be a problem.

The ball joints, if they did go bad, the dealership may try to make you pay for them if they're replaced if they didn't do your oil changes. They may not have been properly lubed (i.e. lube, oil and filter), which is what caused mine to crack.

Good luck, and I hope everything works out for you, keep us posted.

 

P.S. I've had hard starts, I had the fuel pump replaced because of the extended crank time on a cold start. My fuel pressure bled from 60-22 in about two hours. DCX's rule is 20psi in 20/40 minutes. Which my initial drop exceeded. However even after it was replaced its still acting up. I'm taking it in Tuesday to have a co-pilot put in the car to record what exactly the car is doing. The co-pilot is basically a portable DRB that records ALL activity when the button is pressed from 20 seconds before to 20-40 after. If you don't find a solution by then I'll let you know what my dealer says when they take Lucius out and check him again for the hard start. Mines only when the engine's cold and has been sitting for at least 6-7 hours or more. (i.e. overnight or while I'm at work).

 

post does it feel like it wants to keep accelerating when completly off the gas like its at part throttle?

spark ive lost all faith in dealerships no matter what car ive had they all act like they have never worked on that car before or how to trouble shoot.

 

Second issue sounds EXACTLY like my TPS issue....Used to jiggle TPS wire and high revs in neutral would not happen (I bet when you are in neutral, high revs stop as soon as you depress clutch?)....When I installed my BOV, dissconnected the TPS housing and reconnected it under the wire to relieve some of the tension.....well, the solid black and purple wire (if I remember correctly) snapped inside the sheathing, other two wires were stiff, black wire went limp. Did not know it happened, went to test BOV and had no boost at all.....backfire farts and just a real rough idle.... disconnected TPS with car running and nothing happened, no stall or anything....same crappy backfarting.... Thats when I knew TPS was suspect. After replacing wire, car runs smooth....no high idle, revs or anything. Also a little off subject, what a difference replacing spark plugs (with ngk iridiums) and quality wires and a quality Air filter!!!!!!! After OOC, that should be the 2nd and 3rd basic upgrades!!!!!!

 

the second issue is the tps wiring. that's an easy fix, and even if the dealer gives you a hassle you can get the harness for $12 and do it yourself.

the first issue is either a blown axle or a busted ball joint. when exactly does the noise occur? axles and ball joints will make nosies at different times, so that will help. when turning? going over bumps? deceleration?

 

Black4: Exactly. Feels like part throttle when I let off the gas. The rpm's hang around 1700 and slowly raise to 2100, then drop off slowly to normal after shifts if I leave the clutch in and let off the gas. I am with you on the fact that a good dealership is one in a million. It amazes me who these big car companies wil let work on their cars, sometimes.

My dealer is pretty good and SRT-4 friendly so I am going to let them check out the grease explosion going on at the l/f boot. PSI ckick: It clicks when I first start to let out the clutch and go. Not too loud, but I am super sensitive to stuff like this. It occasionally clicks when brake and the engine torque down there is reversed. It does it at every 1st gear engagement. It does it occasionally, in other gears.

Lil spark, I wonder if it will come to a fuel pump replacement, we'll se about that, but it is starting to feel like something is going on with the fuel delivery. I know the throtle cable isn't sticking, my install is flawless ). I pulled the tps and inspected it, and there was a lot of carbon caked around the plunger and it was a little sticky. (BTW the tps assy is the one at the top on the tb, right?) the wire harness is a little tight and it makes a severe downward bend, no tension there, but under load, even with the mm inserts in, I bet it sees a little pull.

Ollie: I am on my fourth set of NGK's and about to order densos and denso wires to replace my msd's. I am with you on the spark delivery, mang. I am a little past the air filter stage.

I am off to go play and see if I can clean the bugger out and make a difference, I'll try a little compressed air at first, and we'll see what next. Hope the wheel doesn't fall off on one of my drives before I get to the dealer.

TTYS, all.

I'm no SRT guy, but I would have to say, CV Joint, and TPS.

Joints usually click when turning, but in extream situations (heavy torque) they will click under initial acceleration!

And, The TPS Sensor would do the exact high idle shoot like you described!

Call Mark or Harry on Monday, they'll take care of it for u.

I'll probably be seeing you monday, jeff(assuming Mark has a spot for me). I'll stop by the tire shack while I'm there this time, I promise. If not Monday, I'll be seeing you one of these days this week. Wish me luck.

 

I'll let you know what they say about mine Tuesday, when they put the co-pilot on my car. I havent lost faith in dealerships because this one has really treated me well. It took me 5 or 6 dealers to find this one, but I did, and I'm glad for it.

I still have a stumble around 2krpms also. At steady throttle, even after JUST having the plugs/wires replaced it still did it. (apparently the TSB was updated to different wires yet again) I'm thinking that the issue is electrical, since my fuel pump/system has been replaced. Again I'll know more about mine, and maybe give you a few ideas on what yours might be tuesday night after I get him back from the dealership.
