1989 Dodge Shadow 2.5L Mitsu T1, 148K, A/T. I just replaced all four fuel injectors with brand new out of the box Mopar fuel injectors, I also installed a new coolant temp sensor. The engine already had Champion RN12YC's (not sure how many miles on them). FPR is still the original. I did pull the vacuum line on the FPR and it was not wet with fuel. I need help in diagnosing Trouble Code 52 pig rich. Code 22 popped up as well, but I have already replaced the coolant temp sensor and cleared that code, so only the 52 still exits.
Cyl's 1,2, & 4 where carbonie (not a word), Cyl 3 was wet with fuel and thus the plug wasclean. Cyl 2's plug was crossed threaded by PO and was not threaded all the waydown in the head when I found it. I have already cleaned up the threads and Cyl 2's plug is seated correctly now. Magnecor wires.
The temperature gauge is fluctuating around too. At idle, the Temp needle goes to one segment above center and the fan kicks on and cyclesagain just sitting parked and idling. If I go drive around the block, the powerseems sluggish and the temp gauge creeps up quickly to hot, radiator is full. After one laparound the block, the temp gauge is about 2 segments from overheat. Runs rough once I put in Park and the fan kicks on late, but does not cool all the way down to under the 1/2 way segment. The OE boost gauge boost's to 4-5lbs at WOT. Idle not in gear is around 900 rpms, in gear it drops 800 rpms and runs rough, definitely seems to be running on three cylinders. Maybe Cyl #3 injector is not getting a electrical signal and just fuel washing.
After the motor warms to operating temps, it does begin to emit white smoke. Its light, not thick smoke. After driving around the block,the smoke is pretty cloudy and stays maybe for 3-5 minutes until it slowlydissipates, but still a light color I can see from the exhaust. I did rev theT/B butterfly from the engine and the smoke got a little more greyish.
When I pulled the plugs Idid not see any coolant in the cylinders and only cylinder #3 was wet with fuel on the plug. Antifreeze looks fine in the radiator. Timing marks are spot on.
Which direction of more diagnosing should I go?
