94 ZJ stalls and rough idle
Ok everyone I'm new to the site and have done a lot of reading online about what seems to be a common issue. I bought a 5.2L, 94 ZJ at auction for 750 bucks! But now it won't idle for **it, It starts fine and will drive great but when I pull up to a light or stop sign it will stall or drop down to 200RPM. The new "problem" is it will idle on start and when you shift to D or R it will instantlly kill. I think its the CPS but want to be sure. I have cleaned the injectors, cleaned throttle body and replaced the IACV. Please help
When my TPS sensor was on it's way out it behaved the same way you are describing but it never actually stalled. When I would stop at a light it would bog down to very low RPM's. On the highway if I gave it throttle to pass it would cut off and bog down as well. I had to lightly give it gas to get it going steady again.
