Ok, this could be a little long. I have a 2000 6 speed manual, 4wheel drive, 4 door door with a 6 inch lift, 5 inch exhaust, and cold air intake.
I had to replace my injectors, so I went with Stage 2 injectors with a single stroke(instead of factory 2 stroke style injector) and purchased a TS six position chip with 30,60,80,100,120 and smoke.
Since everything has been installed here are the problems:
*will high idle once the motor is warm and will not idle down.
*the accelerator is very touchy when driving. Jerky when in gear. I give it alittle gas and the engine will make the truck jerk back and forth.
*when in park and give it gas, there isn't a smooth rpm ramp. will jump from 1100 to 2000 (i changed the throttle position sensor)
*I do not notice any change in performance when switching between the tunes.
My thoughts, Im thinking when the chip was tuned they didn't program it for the single stoke stage 2 injectors. And since I had a shop install it while doing the injectors they might not of installed the chip correctly. Like, to wipe silicone away from the PCM connectors for a good connection.
Any ideas.....could I be looking in the right direction. I thought I would get some feedback before I start digging into it.
Thanks for any help. I dont mess with diesels every day so input from you all is greatly appreciated!!
