KLZE performing bad at high RPMs
Posted: July 29th, 2010, 4:40 pm
Have som problems with my MX3 -92, KLZE.
Have bad MPG, when I changed plugs last time they were really black, so im assuming it's running rich. Also have problems at high RPMs, loses power and it always struggles above 6k (sometimes it dont get past 6.5RPM). Also think it's kind of slow in general.
Currently running KL36/JE50.
I've tried K8/JE50 = bouncing idle, bad low end power, jerking (runs fine only when accelerating), still bad above 6k
Probinator chipped K8/JE50/KL02 - strangely it runs crap with this ECU, bouncing idle and black smoke from exhaust
Kind of funny that i've got a steady idle with KL36 but not with the other two..?
I've changed:
Plugs, wires, fuel pump, fuel filter, new CAI, ECTS sensor, distributor with HEI, changed and adjusted TPS, timing is spot on, no cat.
So the main problem is around 5,5 to 7K RPM, where its performing really bad, i assume because of it running really rich.
Need some input of you guys since im beginning to loose faith.
