My audi A4 1.8T 1998 is idiling low; iwhenI give gas from a dead stop the car will give the fiiling to be chocking, and will take speed very slow; once the car is mooving he accelerate normally, and you will not have a problem untill you stop and start mooving again; if I turn on the AC, the engine will just stop once I push the accelerator ; I will apreciate your help[:@]

I dont think is the transmission; the feeling is of the engine to be chooking; the transm shift beutifull;and I just replace the turbo, becouse this problem, but it did't make a difference; the other turbo was all messed up so I decide to change it and see if the problem go away, but still the same
