Engine cuts at 3000 rpm and back on at about 2000 rpm

When you accelerate in any gear when 3000 rpm reached engine cuts out.

I had this problem a few years back but can't remember what I did to rectify it.

Has anybody had this problem

I had this problem and it was fuel starvation. Once the carb bowls filled up the car would take off perfectly for a few seconds, the bowls would empty and wouldnt run over 2k until the fuel pump caught up. That was my problem but RPM related issues can also be ignition/timing related. Will the car go over 3k when its parked in the driveway? If not you probably should look at ignition as fuel starvation usually occurs under load

If you have a ZX it could be the TPS causing problems. It switches from IDLE to WideOpenThrottle between 2,000 and 3,000 RPMs. It's the little black box on the drivers side of the throttle body. If you loosen the nut you can adjust it. Sometimes they get wet and start acting up.
