Did a search but couldn't find my problem...not sure if right thread or not but I recently bought a '94 Silverado 1500 5.7 tbi z71 5 speed, I believe it has the NV4500.
Here's my problem, truck runs fine. Idles fine starts up just fine doesn't run hot etc.
The thing has like ZERO low end power it will go down the road just fine, takes a bit to get up to speed but it's an old truck with maybe 200 hp when it was new. If there is any sort of incline at all it will rev up and you could red line it and struggle to go 35 mph, in 4th or 3rd. The guy I bought it from put new cap wires coil, not sure about plugs. Doesn't have factory air intake on it. It is high mileage but I'm not sure on the exact mileage. I've got air fuel and spark, not sure where to start looking next...
It's my $700 daily driver and don't have a ton of money to throw at it ( divorce, bankruptcy) first TBI motor I've ever had so don't know where to start...
