Hello Everybody, :wavey
New to this forum so a big hello to all. I have a 94 GT that has a problem with pinging. I have heard that this is a common problem with these cars. The pinging only happens when the air temp get above about 80°. We have checked every thing we can think of. Retarding the timing a few deg is the only thing that helps but then the power dropes off. My car has an auto and a friend has a similar car wiht a 5-sp and we both have this problem.

Thanx for the input

did you try to filled-up with better gas???

Or a higher octane?

What is your timing set to?

Hi and welcome.

Try higher octane?

What is your timing set to?

Hi, Yes I have tried premum and the timing is at 6° BTDC . It's anoying because it should run fine on 87 octane and I run 89 in the winter but it pings
on 91 in the summer. I still think the ethonol in the gas here is part of the problem. Would it help to get an adjustable fuel regulator and increase the fuel pressure to richen it up?


Thanx for the quick replies

i had the same problem for awhile. i always put nothing but 93 octane in my car so i knew it wasnt the gas. but i notice every summer i have to lower my timing. v8s with mods just run to hot but in the winter they run like they got a super charger on the thing. just lower your timing its not worth destroying your engine, every time you hear that noise you destroy your engine more and more. in the winter time set your timing back to racing timing youll see it running alot more powerful then summer.
