no again - another rumor - as effective as killing a sheep at midnight or sitting under a pyramid, or wishing you could find an honest politician.

It doesn't do anything. Just leave it disconnected for 2 minutes. It will clear codes and the volatile (short term) memory. Sometimes the deep internal memory needs to be reset - that takes at least an 8 hour disconnect. If 2 minutes doesn't help, try 8 hours.

You guys should read your FSM more often.

rrich """"""Unhook the battery while your jeep is running. If it dies, then its your alternator. If not, then you have a weak or bad battery. """"""
No, it will always die without the battery connected. A dangerous practice, on on older cars it often would fry the alternator - then when you test it it's dead. But you did it! That test was left over from the 60's with mechanical generators. With the more modern systems, the PCM is the regulator for the alternator. Without the battery, the PCM goes dead, alternator stops charging, engine stops. == wrong conclusions are drawn.

Geno Unhook the battery whilie your jeep is running. If it dies, then its your alternator. If not, then you have a weak or bad battery. Take the battery to Autozone and they'll test it for free.

Also like said a possible vacuum leak, even a dirty IAC or passage can cause an erratic idle.
it got worse. im sure if i hadnt bought a battery charger it wouldnt even start in the morning. just not sure if its the battery or the alternator...

I don't think you have a TPS problem. I'd lean more towards a vacuum problem.
do you know anymore "symptoms" of a vaccum problem? my jeep is having trouble turning over when it sits over night or work shift.

specbill IF it was running fine before the tune up go back to that person and step by step have him reverse what he did until he finds what he messed up. Good luck

98 TJ Tps

I just changed my TPS in 98 TJ, but all the problems are still happening. I thought my tps went bad b/c the jeep was having a hard time turning over and the rpm's would go down quickly and back up while accelerating. I just had a tune up, so I have no idea what else it could be. Any suggestions?
