So I did a tuneup on my 91 Camaro yesterday, and replaced the plug wires, plugs, rotor button, distrib cap, fuel filter, and pcv valve, and after all that, now my car is strong in Park or Neutral if you rev it, but when you drives, it's so slow, like it has no power whatsoever. It barely made it up a big hill today.

We did have one problem when we replaced the fuel filter. We bent the fuel line when we took it off, so we replaced a small section with 3/8 hose and clamped it. Didn't leak at all and seemed to be a perfect patch (we've seen several other people do this patch). I wonder if that has anything to do with it?

I want my car to run strong!

 

If I Was You ... I Would Go Back And Look Closely And Make Sure I Didn't Accidently Pull A Vacuum Line Or Some Electrical Fitting Loose. On My V6 88 RS Eveything Is So Tightly Fitted I Usually Wind Up Pulling Something Loose When I'm Digging Around The Distributor. Sick

 

Did you check the gaps on the spark plugs? Maybe move the distributor to offset the timing? If you're looking for a vacuum leak, spray some carb cleaner on the lines, when the carb cleaner hits the leak the engine should rev higher. Is the fuel filter installed the right way? Some are directional. As long as they're aren't any other kinks in the system, the patched hose should work fine.
