Hey guys, I have encountered a small annoyance/problem with my new 2003 GTP 108k miles... I noticed that the idle isn't perfect, it moves about 100 or so RPM consistantly and then while driving in 3rd and 4th/overdrive I get shuddering. The car seems to lurch then fall off then lurch. Now this isn't dramatic, just minor, but the rpm can jump 200-300 RPM quick while accelerating lightly. WOT is no prob, nor is accelerating in lower gears. Could this be the MAF sensor? My MPG's are still good. I took out the MAF and sprayed it with MAF cleaner, but still does the same thing. I tried to test ohms, but my voltmeter isnt high enough grade to tell if the voltmeter is lagging or the signal is actually jumping. Just want to get your opinions before buying a $100 part. Wish I had a known good one I could throw in as a test. Also need to pray it's not the LIM acting up, but could it be?
Thanks in advance
