Hey im working on a buddies truck('93 PickUp) that has a '00 taco 3.4 installed, and passed by the refs out here in California.The truck was running well but kept burning out MAFs due to the use of a K&N filter/intake combo.I swapped the aftermarket parts for OE today and here is where my problems began.1)the battery was disconnected, 2)junkyard MAF, 3)"custom" emission routing of aftermarket intake. I installed the factory parts and fired the truck up.it ran fine but the checkengine light was still illuminated.I didnt have my scantool, so i pulled the 20A ecu fuse at the drivers kick panel.Remember this is a '93 pickup that originally came with a 3vze.The light stayed on.So the battery was disconnected,OOPS!. The truck wouldnt crank on the first pull,stuttered on the 2nd,3rd,4th.when i can get it to run i have to pump the gas like a carbureted vehichle.it runs better at higher rpms,but is missing or somewhat off.At low rpms it just falters and coughs.I've been searching for a way to relearn the ecu,and reprogram the various modes.Does anyone have any ideas or info??

I don't know about the ECU but here's a tip with K&N Filters

When through cleaning and applying the oil, wipe the filter dry with shop towels.

MAF sensors can be cleaned. By some CRC MAF cleaner, and you can clean the excess oil that came off of the K&N, no need to get a new MAF just because its dirty or covered with K&N oil...
