Sorry can't search for some reason - Coming to work this Am the "check engine" light came on - know this is emissions related - Any ideas on a good place to start looking for problem - oxygen sensor??
Installed the ProMax MAF Sunday - everything has been fine up tot this morning Any ideas ??

 

Quick fix: Unplug the battery for about 60 seconds. It should reset everything.

Outstanding - thanks - will go give it a try -

 

Before you try anything go HERE and read out the fault codes with the gas pedal.

 

Tried the fault code process - my car is a 91 so it should have worked - but, the "check engine" light never blinked once counted to 45 (figured about 30 sec and nothinghappened - Will run a check on the full throttle micro switch to see if that is working - as this was the trigger - Don't knkow if the MAF rewire or system has anything to do withthe failure to display or not
Did the battery disconnect and the light is out - will see what happens now / next
Thanks for the help

 

A check engine light can be triggered by an erratic connection. If you've disconnected the battery, the fault is code's been erased. If it occurs almost instantly when the car fires up it's likely you have a real fault, if not then it's probably a sporadic condition which may or may not occur again. The CEL is great for isolating the spordic stuff because it points to which circuitry you need to be looking at for what will likely end up being a bad connection or wire.

 

Might want to check your throttle pedal adjustment. I know mine was hitting the floorboard well before WOT. You can see the adjustment in this thread. https://rennlist.com/forums/964-forum/274254-first-mod-diy-brake-gas-pedal-adjustment.html

Great link there Jason!
