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 $$$

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.

The mass airflow sensor is located right after the airfilter and can be the source of the problem you describe.

Sounds like it is overfuelling during these episodes.

I would take it to a good injection pump shop. Injection pumps are pretty finiky to work on. They require some special test equipment also. Just my 2 cents. Good luck.

We have the same prob

plugged air filter will result in too lean.not too rich. have the fuel pressure tested. overfuelling will result in the catalytic converter overheating.if the 02 sensor on the catalytic is no good,it will not sense unburnt fuel and the ecu will overfuel. check the air inlet hose and the airflow meter
