Since I've had my Jeep, I'll start it and once I take it down my driveway, it'll sputter and almost stall for a 1/2 mile or so. Once I give it some serious gas it'll all the sudden start to respond.
When it's idling in park or in drive with my foot on the brake the idle rpm's bounce around (+/- 150-200rpms from about 600 rpm) constantly, and when it has large drops it'll go to about 100-200 rpm's then jump back up. Once the problem goes away in the first few mins of driving it doesn't normally come back in that trip.
So I checked the TPS voltage and it starts at .8 volts with fully closed throttle, then at WOT it reads 3.84 volts. Seems a little low to me, but the voltage rose and fell smoothly. Anyone this think this could be causing my problems? I've already cleaned my IAC.
