Hey all, I need a little help figureing out what to do to remedy this little problem im having with knock. I just got my car back from the shop where i had my crank sen, cam sen, ign mod, plugs, and coil replaced and it runs like a dream! They also did a fuel injector cleaning, and throttle body cleaning as well. But i took the car home afterwords, and i was getting one green light on my knock guage just crusin at 55mph not on the gas at all! The shop told me that they filled the car up with about 3/4 of a tank regular gas (89-90 octane) and 1/4 premium (91-92) so i went and got some octane booster thinking that it may need more octane. Dumped that in thinking that may solve the problem, but it didn't...Took the car out and stomped it, and the boost only went up to 4.8#. Yet, i was getting one yellow light on the knock gauge so i let off cause i dont feel like learning head gasket 101. Do you have any ideas what this is? Do i have a fuel delivery issue, or could it be something else?
Oh yeah! the shop also did a compression test and checked the fp at idel, and everything is where its supposed to be.
Thanks again for all the help,
Robert
