1993 Acura Legend REV Question

Hi Rifflelpn,

Is the Check engine light showing?
Was any repairs done prior to this happening?

No check engine light is on. I don't know much about the car because I bought from a tow yard as am impound. I have checked for plugged exhuast and checked the fuel pressure. They are both fine. It's such a wierd symtom that I'm at a loss. Thanks.

Symptoms described could be caused by a faulty/out of adjustment TPS or ECM so these are the 2 items next on your list.

When engine stopped revving at 4000 rpm, it just stays or is it hunting as if the engine is starving of fuel?

The engine just cuts out like it hit a rev limiter. It will start again at about 3700, run up to 4000 and repeat.

Have you confirmed that the CEL shows at ignition ON and goes off after 2 seconds and does not come on while driving?

Yes. The check engine comes on normally at start-up. I have now replaced the TPS and the ECU.

Is the problem still there an exactly the same?

When replacing the TPS, was it calibrated?
