Hey guys, I thought I'd pick your brains on this one. If you could knock some ideas around that would be great. I'm stuck on this one.
First off, all the baseline stuff is in order. e.g. valves, ignition, fuel pressure, vacuum etc.. The motor starts fine cold or warm, and idles fine. However it will not take gas off a stop. It will go with about 1/4 throttle if I feather it. If I punch it immediately it dies. I can also, if up to a fair speed, full throttle it(through the bog) and back it off just a bit and it will take off. Basically it's fine at idle and at full enrich. I'm suspecting a dead-spot in the TPS. (IMG:style_emoticons/default/confused24.gif). Can a bad CHT cause poor acceleration? Enjoy the day Thomas |

Ya, no need to post a pic. It's rich. sooty- you are right, very rich. i just delt with the same thing, that was how i got to tuning the MPS due to the super rich condition, - now i have to go back a step in the other direction- but my gas milage went from 22mph combined to 26!! so i was REALLY rich- had a badly tuned MPS it turns out. had it re-tuned to stock setting and was too lean, so i am working my way back in in that direction. once i get my A.F. meter o2 sensor in place i will better know where i am at, - i agree with the last post, check your injectors for flow, then the cold start valve for leaking. |

I'm in Massachusetts and I have a full 2.0L d jet system in a box -- injectors, mps, cht, brain, tps. If you'd like to "borrow" a component or 2 for troubleshooting let me know.
