Engine doesn't like timing

todd95GT · 10-02-2001, 04:38 PM

First time since I have owned my stang, I had her at the shop. Took a light to it and found the timing was only set a 8*. Bumped it to 14*, took it out, I couldn't believe the difference. My Chevy's never took so kindly to a bump in timing that I could feel like that. Only thing is, it sounded like a shaking piggy bank under the hood. So, we experimented until the detonation was gone, and could only go to a max of 10.5*. Still a noticable difference, but not whee i want to set it at. We were thinking I may just need to clean the TB out, maybe the EGR, probably carboned up or something, then try to advance it again. What do you guys think?

Good Tuneup in general. Plugs wires cap rotor. then High Octane fuel 93. even stock motor mustangs with high timing LIKE high Octane rated GAS. with a 302 you can go as high as 16-18 degrees, or at least I have.. diff cars are diff though

Since I bought the car, I have been running 93 octane because I wasn't sure if the previous owner had already bumped the timing up. Even knowing it is now at the factory setting, I still run the high octane. It's a Mustang, it just doesn't seem right to pump 87 into it, you know?

My 95 also loves timing, but I have bad detonation. My MAF has been going bad though. Tonight it finally grenaded. Maybe you could use an aftermarket MAF. In a couple days I'll tell you how mine takes to the timing advance
