Don't buy the Granatelli MAF outatimejedi80 has for sale. I bought it from him and it threw code 33. I messed with the screw and still code 33. I contact this guy about it be bad. He tells me it can't be bad it worked on his highly modified 89 trans am, I just need to turn the screw alot. So I check my TPS voltage good, check my IAC valve good. I borrowed a MAF from another car and wow problem gone no more code 33. I contact this guy again and he sends me back a link to some website where another guy has a code 33 problem. So I change the relays, replace the TPS and the IAC valve. I cleaned the electrical connectors, added more grounds to the car and cleaned the exsisting ones. Still code 33 install the stock MAF and car runs great no code 33. I contact the guy a third time he finaly agrees to give me a refund, but asks me to cover his e-bay fees. The guy is an idiot don't deal with him or his MAF.
