hey guys I got a new project to work on its a 89 IROC 305 tpi well this is my first encounter with this type of set up, this car would not start with the maf plugged in but would unplugged, so bought a maf sensor and car still wont start with the new one is there a way to test the maf did a search and haven't found anything. Or are there other things to look for ? thanks.

 

Any codes?

 

if youre going to work on it yourself,i suggest you buy a factory service manual. and the first thing to NOT do is buy a MAF from auto zone. try replacing the MAF relays. and yeah. check the codes first. but if it will run with the MAF unplugged ,but not with it connected . I would suspect the relay is bad

 

Well haven't got a code scanner yet but will get one, service manual is on the way. But I did buy a maf from oreilly's and it was a bosche but had a single fin inside could that be the wrong one

 

May be a MAF wiring problem

Thanks I'll give this a try this weekend

 

well guys thanks for the help, I am getting a code 22, I have set the tps and was getting 4 at wot is there something else I should be looking at

 

I tested new tps and its good and I am getting the correct numbers but it is still giving a code 22 even after clearing codes, could the ecm be bad

 

make sure the wiring connector is making contact,with it running , wiggle the connector on the TPS .if it stumbles or suddenly runs well, you have your answer
