My 86 305 TPI T/A was lacking on power, a lawn mower could beat me. I unplugged the MAF sensor and now I can burn the tires off this car. Besides the check engine light being on will it cause any other problems ?

 

No, but its running in limp home mode. Troubleshoot your MAF circuit and it will perform even better

 

dont misinform people.

yes it can cause problems,excessive fuel from it running horribly rich can cause fuel wash on your cylinders,and eventually destroy your motor.

not to mention 99% of tpi cars run like complete crap and suffer from zero drivability with the maf unplugged,or malfunctioning.

like battman said,troubleshoot the thing,dont bandaid it.


do you get any error codes with the maf plugged in? id suggest off the bat replacing the maf power,and burnoff relays. WORLD of difference in my car when i first bought it.

No misinformation here, I have worked on at least five different MAF based F-bodies and ran all of them at one point with the MAF unplugged for various reasons and none of them were running rich enough to wash down the rings. I don't disagree that there is a reduction in efficiency, performance, and drivability with it unplugged. but it won’t cause any permanent engine damage either.

 

[quote=battman;3359803] while you are correct,short term,it most likely wont harm anything,but the poster makes it seem as if this will be a longterm "fix" for the actual problem his car has,which is bad,very bad!

 

I plan on fixing it, the car runs good and is great on gas with it plugged in it just seems to chug when anything past half throttle as if it isn't getting enough air or fuel. NO codes when it is plugged in and fuel pressure is at 41psi. I will replace it with a Granatelli unit soon. I was just wondering if I pull the plug at the track next weekend would the car be allright which it should, the exhaust doesn't smell to rich with it unplugged, if it blows up OH WELL a carbed 355 will go in. Thanks for all the input.

 

I checked my car with the code reader again and it gave a code 33 and 36 which is a bad MAF and bad burn off relay. These parts are still the original ones so after 21 yrs they gave up.

 

did i call it or what? hahaha

 

YA you called it, dead nuts on. I wish that the repair manual that I have would tell me where the burn off relay is, tried to follow on a wiring schematic but the book says the wires are a certain colour and those coulours are not anywhere. Had the same problem with the fuel relay book said certain colour wires and they were different on the car.

 

Mine is located on the firewall on the passenger side of the car.

 

Thanks smityjt, I thought it was on the pass. side up in front of the air box. I ordered one today and will have it tomorrow. Thanks again guys.

 

86whitetpi,

Sorry, I mis-spoke when I told you that my MAF relay was on the passenger side, it is not . My relay is on the driver side screwed into the firewall, its a little black box. I think there are a couple of other relays in that same area including the fuel pump relay I believe. Sorry about that.

 

Thats allright I found it. It actually says MAf Power on it but the wire colours are no where close to what my manual says. Thanks again

 

I drove my T/A to Grand Bend Motor Plex on the weekend, it is about a 2 hr. drive. I drove it with the MAF unplugged and it ran great all the way there I raced it all day Saturday and drove it home on Sun.morning. I used 1 tank of gas the whole time which I think is good, the car never acted up once which made me HAPPY
