My car that is having all of those problems CEL is 71,72,74 misfire code

 

We need more information. Stock?

 

Look at my original post... It's Called my first post. If you can help me you are tha ****!

 

I have replaced spark plugs, wires, cap, ecu (stock to stock) Fuel Map relay, Fuel filter checked cam timing. cleaned TPS and MAP sensors with sensor cleaner. I know I am getting spark and fuel. Whether the mixture is right I don't know, last time I checked my timing was correct. The problem is, I can't start my car. When I push start it it will start and idle perfectly. My car is GSR with intake, header and hollow cat. My car will die if I give it too much gas at low RPM (from idle to 5000) It bogs out and makes a growling noise like I am getting too much fuel or air. I have done everything I possibly can to fix my car but am having no luck. Please help! My compression is cool to about 190-200 each cylinder.
