Dads LT1 VERY sluggish... Title says it all:
94 z28
Car had some rattling noise that has since gone away since the car became extremely "sluggish"
The car basicly feels like it has absolutly no torque at all. No matter how much gas you give it the car can only GRADUALLY increase in speed. It holds speed fine but getting there is the problem. There arent any type of SES lights or anything.
Im not familiar with the Fbody...
I dont know if it would even throw any type of SES...

Its an A4.
I dont think it starts out in 3rd gear... because even at higher speeds giving it gas does NOT raise the RPMs. You still have to gradually ease into a higher speed. What I meant before is that it would just maintain a speed fine...
... except...
... when going up a hill there is an obvious loss of power. On a flat surface you can maintain speed.
It seems to me like it could be something with the torque converter?

I dont know if they are the same but I have an LS1 car and I had the same problem and I got some "QD" Parts cleaner from home depot and cleaned my MAF and the car runs better than ever!

don't forget to check the EGR valve. a friend of mines are was bogging, loss of power when it was warmed up. I also had this exact issue with my 89 caddy. turned out a spark plug cracked, so any time there was a heavyish load on it, it would constant missfire and have no power. the motor was the gutless olds 307 to start, but trying to climb a hill with it was awful. Replaced a bunch of stuff, then I went to check the plugs, and the first one I pulled had a hair line crack in the porsaline. replaced just the plug, ran great!
