ok guys i post one a while back about an lt1 swap i did in my 91 Z. once i fired it up and drove it it would stalls on me when i hit the go pedal. i guess no one has had this problem but any way today i dissconected the M.A.F sensor to see what it would do. i drove the car and it did not stall. does this mean the M.A.F sensor is bad or is it something related to it? also is there a way or can i test the M.A.F sensor? thanks

 

Yep, thats what it is, be sure its getting power if you can scan the car. You'll notice that if you disconnect the filter and put your hand over the MAF, the car will die. Sounds like the MAF is your problem. Thier expensive to replace .

 

thanks pasky. do you know more or less what they run? and will i be able to run it with out the M.A.F for a while or not?

 

About $250 brand new from gmpartsdirect. Dealership here in town wanted $415 . Check ebay for them, cheapest place to get them. Yes you can run without the MAF, you won't see full potential, it just means the motor will run off using the MAP sensor instead. It won't damage your engine if you don't use the MAF.

 

Sorry to hear that but you finally found the problem I read somewhere that if the car is idling and you tap the M.A.F. sensor, if the idle changes, it's bad. Never tried it though. Good luck.

 

thanks again guys. i'm going to see if ican find one one the net. checked with auto zone they want $179.00 for a remanufactured. and thats not what i want. hopefully i will find a new one. keep you posted
pasky your car looks nice in that sig.

 

Thanks, it rides just as good as it looks .

 

If you're looking to save some cash, pick up one from a salvage yard, or someplace like Hawks or Fbodymotorsports. The Lt1 style MAFs rarely go bad (I have never had to replace one), and I'd take used GM over reman any day!

 

well i found a maf sensor on ebay. i got it a few days ago and put it on. it seems to run a little better but i think its something else don't know. still haven't changed the spark plug wires or the plugs. i guess that would be next. if you guys have any idea on this feel free to give some input. thanks guys
