    1995 4.0 with a 1993 swapped engine other than that everything is the same(feel like i should mention that) So my idle cold in the morning will sit at the line below the 1000rpm (700-800ish) however once it starts warming up the idle will slowly drop along with the rise in engine temperature...
  2. TJ Wrangler Technical Forum
    So I just purchased my 99 TJ back in July. When purchased the previous owner said "sometimes the jeep hesitates when taking off" then proceeded to tell me he had the wires and plugs replaced to no avail. I had a similar problem with a 98 TJ i owned in the past and I traced it back to the fuel...

  4. TJ Wrangler Technical Forum
    Hi all, Was wondering if anybody has found someone that carries a gasket for the IAC housing. I have a 99' with a 4.0. I'm going to clean out the throttle body this weekend, but would prefer to put in a new gasket rather than silicone. I called the local Jeep dealer and they can't seem to find...
  5. YJ Wrangler Technical Forum
    I cleaned the throttle body and the IAC the other day. After I was done I washed the engine to try to find the source of a leak. I didn't cover anything up :facepalm: Since then it has taken a lot of cranking to start (5-10 seconds) and then it idles extremely low, near stalling until i give...

    Hey, Jeep TJ Wrangler 2000, 6 cylinder 4.0 - Standard As the title says, when im idle my vehicles RPM start to go up and down. While I am driving, it starts to stumble like somebody is rocking it back and forth. I also have some issues starting the vehicle (sometimes). I searched my problem...
  7. XJ Cherokee Technical Forum
    So I have searched the internet until my eyes started bleeding over this: How does one test - and I mean definitively test - an IAC and a TPS on a 1999 (late model) 4.0L - those threads on renix 4.0L's are all wrong for me - not the right wire count, different sensors, etc. I don't want to...
  8. TJ Wrangler Technical Forum
    Hey everyone, I was teaching my girlfriend stick today and of course it was quite a bumpy ride. She almost stalled it and saved it by mashing on the gas and as she took it out of gear, into neutral. The engine keeps revving at around 2500 rpms. As I was driving back home I noticed that the brake...
  9. YJ Wrangler Technical Forum
    Hello all, I recently got my first Jeep about 3 weeks ago. I traded my motorcycle for it knowing that it would probably need some bit of TLC. It runs perfect except every now and then when I'm making a turn or braking it will die; it doesn't have a slow decline in RPM's, it just dies. The...

    I have a 97 Wrangler. I cleaned the iac today. I put it back together and it would not start without me tapping the gas pedal. Once started it would not idle and just shut off. What do i do? What could've gone wrong?
  11. Engines & Drivetrain
    Hi Everyone, I was hoping someone could give me some help. I have a 2002 Jeep Wrangler. A few days ago my check engine light came on and the code read P1035. I did some research and read that it was an issue with an 02 sensor (bank 1, sensor 1). I replaced the 02 sensor and reset the computer...
  12. XJ Cherokee Technical Forum
    My 2001 cherokee sport stalls out when the car is idling. As the engine warms the RPMs drop until the engine runs rough and dies. I've recently changed the battery, alternator, spark plugs, coil pack, air filter, oil and oil filter, IAC and TPS. I've read on here that the IAC and TPS cans...

    I have a 95 zj laredo V8 and i was seeing if anyone knew how to tell if the IAC sensor is going bad. It idles perfect sitting still in drive, but when i put it in park it jumps up to 1500-1700 rpm.
  14. XJ Cherokee Technical Forum
    Well, I think I am chasing an electrical gremlin. 1999 Jeep XJ, 4.0. I was driving this morning and after about 10 mins my speedometer zeroed and wouldn't move. Then, as I stop at a light my XJ dies. In order to start it I need to give it gas. Soon after the check engine light comes on. So I...

    I have a ZJ 1996 Jeep Grand Cherokee Laredo 4.0L. It idles to low (gauge has 2 marks between 0 and 1 and it sits slightly below the top mark while idling). I have to come to a stop gradually, letting the transmission go into 1st gear or I am afraid the engine might stall. Other then that it...
  17. ZJ Grand Cherokee Forum
    So I get high idle in park and neutral only after driving for a little while. I also have been getting a hard start. High idle happened for about a week, then hard start, so I cleaned the Throttle Body and the AIC with cleaner and also sea foamed the engine. I threw some fuel injector cleaner...

  20. ZJ Grand Cherokee Forum
    I have been having some trouble with my 96 ZJ 5.2L V8. It seems to idle fine (around 500-750), but when it goes from high RPM's to idle - the RPM's go all the way down to anywhere from 0-200. Sometimes it will pick back up and sometimes the engine will just die (but all the electronics inside...
