Having problems with your 1990 Jeep Wrangler ?

1990 Jeep Wrangler 2.5L Idles Rough/Black Smoke / Rich Fuel Odor

\015 Background: I completed a clutch job last month and this is when all my problems started. I thought I might have messed up the CPS, so I replaced with new, nothing changed. After reading FixYa issues/solutions, I ordered a TPS/IAC/MAP/O2 sensor. I replaced the O2 sensor, IAC and MAP and discovered the PCV hose was cracked. Replaced the hose and engine performance returned to normal (no more high/low idle surge). Additionally I conducted a tune-up.\012\012The following is still happening:\0121-Starting cold, engine will turn over to 3000 rpms and backdown gradually to 1000. \0122-Will not start when hot. Have to wait.\0123-Rough Idle\0124-Black Smoke\012\012Questions:\0121- Do I need to change my oil? Could fuel have mixed with oil?\0122- Does the injector normally tick?\012\012My last options are to change out the TPS, Fuel Injector, Fuel Filter, Fuel Pump. \012\012Any thoughts??\015 Posted / edited by AnonymousUser on : 21-01-2019
