It could also be one of the temp sensors. Likely the one back above the rear of the IP. I;ve been suspecting mine for a bit now.

Does anyone have/know the test specs on them?

Since the k40 supplies power to several of the sensors, I'd take a close look at it and either re-solder suspect connectors or just replace it all-together.

Aside from the k40, I think these cars are not designed to accelerate when you have foot on brake. Check the brake light switch. If its on it might be causing your acceleration issue. Whereas in neutral it doesnt come into play. Just a thought

i think since it happens with increased temperature that it would be the k40, because it malfunctions if it overheats. if you have a friend that has the same car try his k40 before buying a new k40. They are not that expensive anyways

new update , when car warm, in drive car will move slowly then build up momemtum, If put car in neutral and hit gar car revs slowly , then builds up. seems to not want to rev off line whether in gear or not, so not trans problem. Any ideas?, again all filters new no fuel or air leaks, have to pull injectors and have tested. Thnaks
