Hey guys, i havent been around for a while but I got a new truck a few weeks ago. its a 95 Lightning. I will post some pics in a bit, but its got a small quirk. When its in park it doesnt idle right, it stays up around 850-950rpm when its in drive its fine. it also doesnt do this immediatley after you put it in park, it takes a little bit and it slowly goes up. also when you start it up when its semi warm, the idle will surge for a bit. Ive already cleaned the TB and the IAC, and also checked the EGR. could it be a vacuum leak? I also didnt notice it untill i put on my under drive pulleys and FIPK. what do yall think?

 

here it is

 

Nice truck

 

Sweet truck. I always loved the early lightnings, and the white ones always seem to look the best.

Does it have any codes? You might get an voltmeter/ohmmeter and check the throttle position sensor.

 

i havent scanned it for codes, but i have no check engine light. I already checked the TPS, it was within range but i set it to .95 then reset the computer, it didnt change anything. what about ignition timing?
