Hi eric

Thanks for helping me so many times past these years! Last year I was soo close (about 12 hours drive) to reach your meet up.. Now its 11 hours flight.. But.. My AMA is what could be wrong if my car bucks and feels like missfiring and no power when driving over 60mph going to a little uphill.. Recently I replaced ignition components such as sparkplugs and wires, checked coils and they are in specs.. The car is 1994 “General Mistake” vehicle with notorious 3800 engine..

Greetings from Finland

Thanks for the reply.
I really have to try that leakdown test. I never thought that test but It will definately tell me what is going on. I will try that next. I dont know when I have time to do the test, but when I get it done i will tell you. 🙂 I know its not impossible but it is really pain in the butt because theres all kinds of stuff in the way.

Well.. I noticed that when car was running there was steam coming from right side of the engine. Also when i topped up the coolant and replaced leaking cap the car was running rough for a minute and then it was impossible to start it again.. So there was pressure building in the coolant system cause the new cap and then forced the coolant in to cylinder? So faulty head gasket? Im just guessing but its not possible to do compression test because theres just not enough space.

I have tested fuel pressure and I think it was in specs. I maybe have to check it again. There is fresh fuel in tank. When I get it running it blows black smoke and smells very bad.
