Throwing Codes!
Throwing Codes! Ok. I own a 02 z28. Ive done heads, cam, headers, intake, true duals, tune, 70 or 72 mm slp MAF. I got it tuned a while back in florida, sadly I got stationed in Michigan. Recently the car has been throwing numerous codes.
P0106 manifold absolute pressure
p0300 multiple misfire
p0200 injector control circuit
1 other, cant remember
What I have done to "TRY" and fix the problems
1) check all wiring from the battery in the trunk, forward.
2) Ran Noid lights to each injector (all pulsating)
3) checked spark plug wires and firing ( Screw driver to the ends of each wire test)
4) checked the fuses for the injectors
5) checked battery with snap-on tester
I can't figure this out. Its getting fuel, actually running rich, probably not the best to have fuel spots under the exhaust ( texas speed true duals sweep downwards). Its getting power to each cylinder. I could probably check the spark plugs in the morning. Any questions or fix ideas would help!

I'd check that the MAP sensor isn't broken or unplugged. It's located on the back of the intake. Also, check for blown fuses and bad grounds (on the back of the heads). Make certain that the plug wires are on all the way. Good luck.
