yea I guess my valve stem seals are due it has been 14 years! but still no smoke on start? I will check the plugs for yellow deposits they are due also anyway. I am also going to replace the sensor on the head mine is a 2 prong.
it is the last one on the back of the head that tells the fuel inj syst the eng temp. I like what one of the guys said about the bog or dead spot with a heavy foot. I also have this symptom. makes alot of sense. I will order one of those also. I have been neglecting this poor car since I got my 96 SL500. That thing is a handfull with the ASR ABS lights on,but thats a whole other post. Thanx John .I will update when parts are rpl...........................
