misfire/sputter
 
i have a 97 wrangler 2.5 ltr after i drive about 3 miles it starts to sputter and misfire i had the codes read and it said there was a problem with the throttle sensor, which i replaced but i still have the same problem, i also changed the map sensor,camshaft and crankshaft position sensor and plug wires ...i'd appreciate any words of wisdom because this is really getting frustrating......................

I've got the same model as you, and mine when i first fire it up and start moving, it bucks and sputters until i jam on the accelerator and get the rpms up to at least 3 thousand. I havn't done any mudding or anything so could I have the same problem as you and what the other thread was talking about?

did you find the problem??????????????

I had near about the same problem with mine when i first got it from the dealership. Its an 01 TJ. The check engine code was reading TPS. Changed it myself but still didnt fix the problem. After alot of research i found out the TPS has to be installed by someone who has the cpu reader. On the 01 at least i know the TPS is adjustable and even putting a new one in it wont fix your problem if it isnt adjusted and calibrated with the computer. After that it has run like a dream since.

mine was a cracked head. but mines under warrenty still so it free to replace:D the only problem was the crappy retal they me. did u change ur spark plugs, it could be a blown head gasket?

Strange thing about mine is that there has never been a check engine light. Could it still be spitting out codes without the light?

The link below is a LONG read, but it looks like many of the 97 TJs have this problem. I was able to change the front O2 sensor and stop the problem, but others had to do much more.

***** Major Find******
 
:eek: had the wrangler idleing today and removed the oil filler cap and found i have what seems like exhaust blowing out through the valve cover. How can i determine if its the head, head gasket or whatever else may be causing it???????????:eek:

i unplugged a sensor on top of the rear transfer case and now my jeep runs fine , can anyone tell me what this sensor is called ????
