(d21 motor) I changed TPS sensor iMac sensor distributor even computer. Checked for air and vacuum leaks, cleaned out EGR valve, put new spark plugs, changed ignition control modules, and coils. This truck still does not run right. It idles good and drives good as long as I baby they gas pedal, once I try driving it hard it lurches and cuts out then I let off and it gets back to normal. I had fuel pressure checked also and it is good. I put new catalytic converter. I put fuel treatment. When I push pedal all the way down it cuts out at 3000 rpm like it has a rev limiter. I am loosing my mind in this freaking truck. Some one please help. I also want to mention it is a four cylinder with the eight plugs and fuel injectors. I also sprayed starting fluid with throttle fully open and it still cuts out.
