Check the fuel pressure regulator if its overfueling.Pull the vacuum hose off the regulator and look for fuel to run out if it does replace regulator.Do the same with the map sensor.

Unlikely this is being caused by ECU. Not impossible, but unlikely. For poor spark, ECU has nothing to do with this. Check ignition module/coil. For overfueling, bad spark can prevent burning fuel properly, but leaking fuel injectors or bad coolant temp sensor more probable.

I have a 1997 2.6i microbus its overfueling tried changing map sensor computer box injecters fuel pump but its still overfuelling. What is wrong with it ?


Have an OBII scan (fault scan) done. Any good shop or parts store can do it for you (most will FREE) and get the codes (faults) to identify what needs replacement or adjusting - instead of throwing parts at it. It will save you $$$

i've never heard of a cold temp sensor... theres an intake air temp sensor it goes in the large plastic tube that comes off your air filter box, i doubt this is your problem tho.. i would lean more toward the fuel pressure regulator or one of the injectors could be dumping. also a clogged catylitic converter may cause an overfueling situation. hope this helps and good luck
