Hi All,
I just finished swapping out my frozen a/c compressor(PIA) and got everything back together and took her for a spin. I tried to start and the first try(15 seconds of cranking ) produced nothing but then immediately tried again and started instantly. Seemed Ok but missing A little power. Got on the highway
and going uphill at higher RPM engine was at maybe 50% of normal power. Barely held 55 at max pedal going up steep hill. No pinging but making a subtle strange
air sucking(strugggling to suck kinda)noise. Can someone tell me what I screwed up or knocked outta place?? Please...
Thx
Matt

You should check the hose going to the mass air flow sensor, if loose the engine will get air the computer don't know about and the car will run lean.

Thx that was my first thought too, but it is solidly in place(even cranked the
buggers a little tighter), Catalytic converter?

The hose on my demo car was rubbed through on the inside, but I never knew it till I flipped it up to run it through the hood. A little duct tape fixed it up nice. A converter can get pluged up, but normally that only happens on cars running very bad. Burning lots of oil or overfueling. Also second choice is a loose coil wire, or loose ground wire, since you were in that area too.
