Author Topic: Running Rich? Wildfire532FB CAFords OG Member # 1482 posted                                 My Jeep is running really rich, so rich that after driving it around for a bit and then shutting it off it won't start back up for atleast an hour afterwards. What could be causing this? The Jeep has a 92 5.0L [ June 20, 2005, 05:31 PM: Message edited by: Cobra5.0JEEP ] -------------------- ./_ _ _ ___ __\ (]]]_ _ o _ _[[[) |\_o_ __ __o_/| |__|..........|__| 68 Fastback 84 CJ7 94 HMMWV 95 GT 03 F350 17 Fusion Hybrid Posts: 17578 | From: 530 | Registered: Jun 2002  |  : 92stangLX ¯ Member # 3252 posted                              Pull codes from the computer. I could be your MAF. It kinda sounds like it is in "limp home" mode. You could also have bad O2's but I doubt the thing would run that rich.

It's pooling fuel on shutdown, flooding the cylinder. Pull the plugs, see what's up. -------------------- 1965 Shelby Cobra 1993 Cobra 2012 F150 Raptor 2020 GT500 Posts: 6523 | From: Orlando FL/Redding CA | Registered: Mar 2002  |  : 2stangs69-91 ¯ Member # 1951 posted                              I have also seen fuel pressure regulators cause this problem. When they stick you can be pumping to much fuel in everyhole not just one. It doesn't sound like one injector sticking to me. the car would still fire just have a dead hole until it cleared out the excessive fuel. -------------------- 69 Mustang on hold 1991 LX hatch getting a make over 1994 F150 4X4 351 2006 Yamaha V-max 1200 Modded Posts: 3711 | From: Redding | Registered: Oct 2002  |  : Wildfire532FB CAFords OG Member # 1482 posted                                 That sucks If its the injectors i'll just upgrade to the 24s sitting in the garage with a bigger MAF and maybe throttle body. If its the regulator thats fine too i guess. I don't wanna do the work though haha. I thought i just got this damn thing running good but i've noticed its trouble starting after running for a while and now sometimes it won't even start I broke the engine mount on it pulling the old 600lb car lift out behind the garage, the thing dug in and jerked the entire car Its ok though stupid mount bolt always breaks i need to modify the engine mounts so that they don't break bolts anymore. So i will fix that first and then check the plugs. thanks guys.

My Jeep is stuck down in downtown GV right now All it does is turn over and floods the engine. Sounds like its not getting ignition at all. It has a MSD ignition on it. -------------------- ./_ _ _ ___ __\ (]]]_ _ o _ _[[[) |\_o_ __ __o_/| |__|..........|__| 68 Fastback 84 CJ7 94 HMMWV 95 GT 03 F350 17 Fusion Hybrid Posts: 17578 | From: 530 | Registered: Jun 2002  |  :
