Groovy, tps tps tps. Theres no issue. Tps has lag from relaying through the pcm to the throttle.my truck is the same way.

 

So it's normal to have to almost floor my truck to the point of downshifting to increase my speed on the highway??

 

I have had this same lag, as well, but what I experience is pretty minor not anything like what is happening with groovy. I went to this link
and Off_Road says that this procedure is

Does anyone know if this is actually the case? The thread says it comes from the Service Manual but I could not find that. Here is what is written in the Service Manual for this calibration for the ACCELERATOR PEDAL POSITION SENSOR and for the THROTTLE BODY:

(this is from the APPS Installation section)
(7) Perform the following procedure:
--(a) Connect negative battery cable to battery.
------ It was disconnected in the Removal section...
--(b) Turn ignition switch ON, but do not crank engine.
--(c) Leave ignition switch ON for a minimum of 10 seconds. This will allow PCM to learn electrical parameters.
(8) If the previous step is not performed, a Diagnostic
Trouble Code (DTC) will be set.


Does the pedal have to be pressed and released?
Is clearing the fuel delivery schedule, by disconnecting the battery, required?


groovy, did you try what Hammer linked to see if it made a difference?

I have reset the TPS as Hammer instucted but haven't been on the highway yet. I will try today and post the results.

 

I got out on the highway today.It did seem a little better at 65-70 than before but now at about 45-50 it seems to be acting up. I'll drive it a little more and see what happens.

 

Diablo has a throttle sensitivity adjustment in their tuners. I know on mine I can push down on the pedal slightly and it drops down and MOVES!!

 

Might wanna put a meter on your tps and see if its in spec

 

You may also want to have someone else drive your truck and see what they think. I've had people ask me to drive their trucks because they are sure they can feel a lag, front end vibration or other problem that I can't detect.

I'm not saying you fit in this mold, but I have a friend who has a Chevy Z71 and is fairly active on the Chevy truck forums and EVERY truck ailment that he reads about on the forums he has the next day - the guy actually losses sleep at night after reading about some guy saying he heard a tick for a couple days and then his transmission blew up. This guy will get out of bed at three AM and start his truck up to listen for a tic, then of course he'll call me up and hold his phone to the engine wanting me to listen to it!!!

This guy is an extreme case (and an extreme nut job) but my point is that sometimes when we think we feel/hear/see something we make ourselves believe it's there or worse than it actually is...

 

is there a c-code 67 27 for a 04 ram 1500 4x4 5.7 hemi
