I have a 1997 4cyl 2.5L wrangler with 200k.
Most parts on this vehicle have been replaced over the years.
Recently replaced manifold with a header as old one was cracked. (Seems that my ex mechanic/boyfriend put some parts on incorrectly. I was told that the old manifold cracked as it was improperly installed).
Jeep ran great for 3 days. Yesterday Check Engine Light re-appears. Says O2 sensor (which has been replaced many many times) and now gives error code 24. Idle is all over the place ranging from 2000 to nearly stalling out at which point the oil pressure gauge is falling to 0 as well.
Anyone have any idea what could be going on here?
Any suggestions would be very much appreciated.
