I have a 95 T/A M6. I can rev the motor up fine when not in gear, But I cannot rev up fast when taking off, It will bog down. I can slowly take it up to any speed, When I shift, I shift at 3000 rpm, cause it will start to like cut out. but I let off the gas a little, and it steadly picks up speed.

Anyone have this happen before, I am not throwing any codes, and my check engine light only comes on if I floor it, of course the car bogg's down at that point, and when I let off, the light goes away.

 

My guess would be distributor

A scan for soft codes would tell you what that light was which might help. Having seen this in older cars, I'd say plugs. How long have they been in there?

 

I have only had the car a couple weeks, and have done nothing to it.
I dont even think it the owner took car of it, the oil was black, the air filter
is pretty bad . I was thinking a good tune up would and should help. 133000 miles on it.

Bosch platniums ok for plug's?

 

Sounds to me like you have a bad plug and or bad wires. Unfortunately replacing them is murderous hell on your hands and back but it will most likely(99% certainty) take care of the problem. And bosch plats work for me.

 

Factory plugs are always best in any vehicle if it's mostly stock. Spend the extra money and go with the AC Delco's.

 

Clogged fuel filter?

 

Its dirty, but not really bad. I cleaned it with some good hits to the ground,
till I can get a new one.

How do you know when you need new O2 sensors?

 

Im gonna have to say opti is goin out...

unless you have like 6 burnt wires...

 

yea, plugs... go NGK TR55... delco are overpriced and bosch suck
