Codes
--------------------------------------------------------------------------------
This is for a MAPs controlled 302 in a F-150
With the KOER I get these codes 116 which is ECT outside test limits
173 HEGO shows system always Rich
538 Insufficent RPM change during KOER dynamic test
632 Overdrive Cancel switch not changing
I have what feels like a miss in the truck. I guess a studder could also describe it. It used to be in over drive at lower rpm's but now You can feel it in drive while going 1500-2000 rpm aswell. Also not a smooth acceleration from a stop. Kinda a jerky acceleration. When backing the truck up many times it will stall. Black smoke from tail pipes as engine almost dies then surges to higher rpm and back down till it finally dies. Takes a bit of cranking to get it to start again like it is flooded. There was a new o2 sensor installed less then a year ago. I have a comp cams computer controlled cam. .060 over pushrods. Shorty headers off road h-pipe and a flow master cat back. The reverse stall would happen before the cam was installed. Any help would be helpful. I have the TPS set to .82 volts i believe. I cleaned my IAC aswell. My TB was also cleaned thourghly. thx in advance
