Well check the timing again.
Was this just with the hot weather we are having? U can also check the plugs and see if the car is running lean. |
pull the plugs, replace them, gap them a bit tighter...
until we know the timing, we can't help you though. |
Timing should be 10 degrees. If it's 14 degrees, you need 94 octane.

Clean the MAF..

thanks
thanks dudes the pinging is gone thanks to quaker state f.i. cleaner one dose in a green aluminium bottle it works. after letting it do it's job for the last tank last night was tryout time and a vast improvement in acceleration it even spun 2nd gear(auto).I guess it really was owned by a little old lady before I got it in april. wow a honest used car salesman who knew!
