Possibly serious issue
Under heavy acceleration the car will run smoothly then all of a sudden lose some power and the check engine light will turn on. It will still accelerate but feels more Honda civic-like. doesn't seem like the clutch is slipping, doesn't rev disproportionately to acceleration, just slows down. Any help would be appreciated.

Does your car throw codes? If so, maybe the reason for the check engine light is stored in your car's computer somewhere.

Could be anything. Get the codes. Mine was doing something similar at one point. It ran fine but under heavy acceleration it would fall flat and run like a 4cyl. After a few days I discoverd this in the pic below.
The air duct was cut and on heavy acceleration it would cut off the air supply.

I remember the guy i bought it from saying it doesn't throw codes, but its in the shop now for a rear main so ill have them check fuel pressure as well. Took it to a friends garage a week ago and he said everything was fine, now I'm in for a rear main, possibly injectors and he left my tranny, o/d unit and rear end almost bone dry.

also, a stopped up fuel filter will cause it to loose power on the top end. But usually with that, it is a miss as well. Again, I would look hard at the converters.

Check for stored codes should be the first step. Most auto part stores will check them for free.
Sounds like the fuel pressure regulator (FPR) is busted....but this shouldn't really throw a code....
