I am brand new to the group so not sure if I posted my question correctly, so, I will try again. My 1998 GS300 has just under 150,000 miles. I put 100,000 of them since getting the car in 2001. Have always kept it well maintained and never any issues. Last year it started leaking oil from (I think) the head gasket? Anyway the one which is labor intensive to replace. The check engine light has been on pretty much since the leak started, altho I always keep the proper oil level and have been using Castrol Full Synthetic as the years and miles have accumulated. I assumed the light was caused by the oil leak. Then before making the appt. with the repair shop, I slowed down to turn, had to stop for traffic, and the car ran so rough and idled so slowly that I had to gas and brake at the same time to raise the rpms till I could make my turn. At the same time as the car started to run rough, both of the VSC lights came on and wouldn't go off. I (unfortunately) was not who dropped my car off to be fixed, and apparently the guy only replaced the gasket and the timing belt but claimed not to see the lights nor feel it drive rough. Had I been the one to take it in, I would have made sure he knew those issues going in. Anyway, I picked it up, and before I got to work the lights and rough running came right back. I took it back, told him the issues, he kept it all day and said there "might have been a speck of dust" or something on something they replaced, but now it's gone. I told them to drive it a good little distance, and don't drive it like a granny either (I drive it like the performance car it is, always have). Again, he denied any more lights or roughness. And you guessed it: same thing. Mind you, this is after he's been paid nearly $2000 to replace the gasket and timing chain. Certainly hasn't fixed these issues. I'm taking it back tomorrow and have much less patience than my husband. Thoughts?
