Just finished a full hi performance build on my 93 z28 lt1. First startup broke the cam in but car was idling erratically and found that 2 plugs on distributor on backwards. Than i started it and let run 4 a bit and cant get 2 start again its running way 2 rich. I had new 36lb injector in so i put the stock 22lbs bak on and took all the plugs out cuz they were flooded and burnt but even when i put bak in it almost fired up. Wtf is goin on help pls?

Do you have a base line tune to start with if not that your first mistake

Yeah no matter what it's not going to run right with out a tune

No i dont have any sort of tune. It started up and ran tho with my 36lb injectors and than the next day i started it up and it didnt run long b4 it wouldnt start again. Is the computer overloaded or sumthing or is it mechanical?

You need a baseline tune. And there is no breaking in a cam, you put it in and go. My car was the same, it was running way rich. I had to hold the throttle open to start it and to keep it running on a baseline tune

You can't simply swap injectors without programming the PCM. Running those 36# injectors will dump 35% more fuel than what the PCM is thinking, which can do some serious engine damage by washing down the cylinder walls. Stop trying to run the motor UNTIL YOU GET A PCM TUNE. I recommend www.pcmforless.com.

Also there's no break-in for a hydraulic roller cam. Fire it up and go.

Stop trying to start it! Send your Computer out to be tuned for the engine mods you have so it will actually run half decent and not cause potential damage to your investment you just built! Once its tuned and doesnt start come back and let know where your at.

The tune will help your car run period. Think of the tune/pcm as the brain of your car and the engine as the heart; the pcm is going to tell the heart what to do not the other way around!

by the way if you have a 93 you don't have to send your PCM off, they will just send you a chip to piggyback the PCM. While you are waiting you may want to pick up a dattalog software and a cable to start reading and scanning your car, so you can get a close to spot on tune.
