Alright, I have a 89 iroc with the tpi 350...I am looking for a new mass airflow sensor and do not know exactly what would be compatible. Are all 82-92 one's for tpi engines compatible?

All I've seen from reading post after post is bosch and delco..many on ebay don't tell what company they are from though.

Some are really expensive, and some are pretty cheap (some used). I'd like to get the right part...got the wrong injectors lil while ago and ended up costing a bit of time and money. Thanks-Chris

 

If you are going to buy one I would get the Wells MAF. With screens it flows more than the stock one without screens. I have seen prices quoted at around $170 for the Wells MAF. Someone may have more info. Allen

 

If I were you I'd personally go for a new Wells Su145 MAF.

I wouldn't risk parting with the cash for a used MAF sensor. Chris, have you confirmed that you MAF sensor is knackered? Have you tried running without it connected?

 

However, in internet land there are always varying opinions and different people will say they had problems with different parts.
