but could it be something else.... injector tick or something... i have a 1991 mustang 4 cylinder LX and when going up hill, the engine i think pings hella bad... it is at stock timing, about 10* or so BTDC. I put 91 octane in it, even pings on 110 race gas... i put some of that in there to see if it would stop but it still does it...if it was a clogged fuel filter it would run like crap right??? this thing runs perfect just pings.... and i know that cant be good for it... it usually runs at about 170 or so on the temp. so i know it isnt to hot either... anyone have any ideas??? thanks

Isn't your 4 cyl mustang hard to start on 110 octane? Any codes from the computer? A dirty fuel filter will only reveal itself at higher RPM's/loads where the extra fuel is needed.

Well the problem is you have a 4 cyl.Somewhere it tells you if you that if you have a problem with it to replace it with a V-8. [Big Grin]

But seriously every 4 cyl Mustang I have had,although they have all been turbo SVO's have had the pinging problem uphill.Welcome to a shitty design of an engine with lil to NO torgue that for some reason sucks under a load therfore sucks ass uphill.

BTW that race gas you used was it leaded or unleaded?
