Acceleration glitch?
OK, I have been trying to take care of this problem for a few months and now I am getting to a low point in the troubleshooting.
86 944 NA 5 Speed. While stepping on the accelerator, dosent matter if it is hot or cold, feels like it is stumbeling a little bit. You can step on the gas pretty good and it will go, but as it is gaining spped, it seams to be like it is missing, small amounts of power loss. Not a major jolt, but enough that you can feel it. Suggestions? Changed the Fuel Filter Dec 07 Ran Injector Cleaner in Dec 07 Installed NEW O-Rings and seal on the injectors Aug 07 Installed NEW FPR this last weekend Installed NEW Plugs, Rotor, Cap and Coil within the last month Don't think I have a vacc leak, but I am in the process of replacing with a new kit. My last thing I am thinking is the DME Computer, but Not too sure that is what the Haynes said. Thanks for any help.

Yeah ^^ I just did mine a couple days ago and made a video of it. See if this helps. It straightened mine out pretty well.

Hello, I follow the link but the video doesn't play for me. Anyone else having this issue? I'd like to see or get a copy of it, thanks. Ralph

Try doing a search on youtube for "Bosch Motronic" and it'll come up.

Just a thought, I was having a similar problem awhile back... turned out to be the oxygen sensor... as a quick test just unplug it... if this is the problem you should see an immediate improvement... of course, you will need to replace it with a new one to avoid running too rich.

The oxygen sensor could certainly also be causing problems, especially if it is old. Actually, I have a thread going, covering the same type of problem, including how much fun my oxygen sensor replacement was.
