Engine Performance problem
1989 Mercedes Benz 300e Front Wheel Drive Automatic 110000 miles
I have a 1989 mercedes 300e. Sometimes my car acts up. When I turn it on it has trouble staying on, it either idles really rough for a while or stalls out. This happens usually just on rainy days or if its cold. When it stalls out I have to rev the engine until it is warmed up, and when I do I push the peddle down a little bit and it revs, for a second, then acts like im not pressing on the gas and decreases the rpms, then it goes back to revving and continues the up and down thing. I want to know if anyone has any idea because after I do this for a while it runs fine.
