Hey my acceleration is stuttering it sounds like it is misfiring, it does it at about 4000 RPMS-8000 no matter what and under 4000 it will do it occasionaly, and the idle doesnt seem to be doing as well. I changed the spark plugs and the timing seems good. It was running fine till the other night when i got back and was adjusting a ground wire it's one that goes into the main fuse box. I also messed a little with a MAP sensor but nothing big. what can cause this stutter and slow in the accelleration to happen?

 

It could be a hole lot of things. I know for a fact that bad gas will promote these sort of malfunctions. What else is new? Have you changed anything lately? How many miles are on your vehicle?

 

I had the same thing happen AFTER i brought the car to the honda dealer for a master coil. Happens until I hit higher RPM in gears 1-3. Happens especially when I have the A/C on. Premium gas did help but plugs and wires for YOU may be an issue, timing ?
