I have a very small miss in my engine. You can feel it the most when it's at low RPM's while accelerating. I changed out my MSD coilpack for the stock one and no go. Changed out the wires for the stock ones, still no go. Changed out the plugs for the stock ones and still no improvement. So I thought maybve the stock coil and MSD was bad and I picked up a new one and still no difference. Any ideas? I'm thinking maybe the TB is bad and it's not really a miss at all. You can't really feel anything at higher RPM's while in neutral, just a very, very slight stutter once every few seconds or so. When I had the car dyno'd the #'s were about right for the car compared to other cars. If you have any guesses post them and I'll check it out.

 

octain?

 

I run 93 octane every tank

 

Small head gasket breach?

 

Almost brand new engine with 15,000 miles on it. I'll check the compression though and see where it's at.

 

Call me crazy, but do you need to run 93oct on a 4dr Escort that makes 80hp? I mean you running a higher oct. then hp. To each their own I suppose.

 

LOL, I like the cleaner burning fuel I don't think it affects anything by running that it's not like I use that much money for gas anyways. Takes me $19 to fill up which lasts me about 320-370 miles.
