I brought it in a couple weeks ago for the IC pump, or so i thought. It had all the signs of a bad IC pump so they replaced it. well It is not fixed. I have a johnson IC pump sitting next to me but shouldn't a brand new IC pump from MB work if that was in-fact the problem? If i go full throttle from about 40 to 120mph after that the car is a dog for 5 to 10 min. I have lost numerous races because of this (inc a crappy 5.0 mustang!) also around 1800 rpm the car seems to miss a step. Its under light acceleration and its almost like the fuel is just cut for a split second. Now yesterday a check engine light came on. Also my transmission like to pound the car forward at goofy times under slight throttle up shifts. I would assume the tranny problem in unrelated to the others. The tranny problem is much more intermittent. What's wrong with my car! I know these cars are very well built... anyone have any ideas?

 

maybe you need to send it in for a full diagnosis...it's may not always be the IC pump you know.

 

CEL came on,you have problems.Take it to the dealer.

 

I got my trans and torque converter replaced due to that jerkyness from 1st and 2nd and when slowing down.

its alot better.. but I can still fell some jerkyness when slowing down..

I also got my kompressor clutched replaced..

take it in.. or have someone scan it for you.

 

it's kinda of a good thing the CEL came on, it should be easier to get to the problem now that it has stored a code, first thing get it scanned and see what made the CEL light come on and work from there

 

ok it's at the shop! hope all goes well

 

Don't let them flash your TCU, they did mine and put it grandpa/comfort mode. The sifting was soft and the car tries to go into third before 15 mph.

 

interesting thread...Any update if the problem was fixed?
