The startup flare is normal. So long as it comes down to around 1K rpm when cold, and around 600 or so when fully warmed.

The platinum plugs were a waste. More often than not, the engine doesn't like them, and you get a miss, or other odd running behavior.

Check TV cable adjustment. Should be no slop in the cable, and it shouldn't be pulling the arm on the trans off of its stop either. There is and adjustment procedure in the service manual, which you can download from the 2nd Gen Faq section. (in the service manual thread. Get the 2001 version.)

Reset your PCM. (disconnect the battery, turn on the headlights, turn off headlights, reconnect battery.) Drive it for a day or two, and see if anything improves. If not, take it back to the trans shop.

Gonna move this to second gen tech for ya as well.

Need to check and see if you plenum is good. If you truck is high mileage, (over 80K) probably want to replace at least the front O2 sensor as well.

 

havnt checked on plenum but yea shes got almost 200,000 & im tryin to keep her goin lol. I just changed my lower o2 about a month ago (it put the light on & shot me a code when checked) but I have the upper on my 'to do list' -bosch the best bet? or is there a big difference? (order thru jc whitney allot)

 

Skip Bosch. Our trucks don't really like their O2 sensors. Go with NTK, or Denso. (both available from Rock Auto for a reasonable price, plus, discount codes in the general discussion section.)

With 200K on it, the O2 sensors are more than likely toast. (slow response, won't necessarily set a code.)

 

well I think I narrowed it down to the plenum gasket so im going to change them as soon as I get the chance. got the basic idea but wondering if ya had any advice before I get started on that? >id like to go with the thicker plate but truck budgets drained. lol

 

If you have to go with the OEM steel plate, grind the ~1/4" unthreaded portion on the end of the plenum pan bolts off before you put them in. If you screw one in without the pan or gasket, you'll see why.

 

would it be better to just grab new bolts? also are there any real 'tricks' or unexpected problems, parts, ext? lol -thanks again 4 all your help!

 

Do not use any type of silicon sealant on the plenum gasket, if you use anything aircraft gasket sealer is the best bet for that job. I like to suggest that the lifters get replaced when doing this job 8 out of 10 times people get back on here and they have a lifter tick and have to tear it all down again.

My list just for the plenum job.

Theses are Mopar performance part numbers, they are cheaper than just stock replacement parts from Dodge. Some parts are the same as the stock ones others are better.
