    Well , my car was running fine with an occasional check engine light on heavy throttle. I just replaced my heater core. Now when it reaches temp and I push on the throttle it cuts out and makes a pop in the engine bay. The only mod done to the car that I see is Off road H pipe. Also looks like a tube that is part of the smog system is pinched off. This is how I bought the car. Thanks in advance .

    Low fuel pressure will make it fall flat when you push on the gas. Check the fuel pressure.

    Does it cut out only under load or will it cut out just revving the engine?

    Well last night I have everything back together and had it running in the garage for 45 minutes. It seems to have fixed itself . Maybe because there were some connections in the dash that were not connected it would do this. Anyway it runs as it did before I took the dash apart. Thanks everyone.
