HI there. This state is called limp mode. When the engine computer senses a serious issue within the operating status of your engine, it will initiate this safety mode, which in return, causes your vehicle to not exceed a certain mark. This state is to prevent further damage to the engine. There may be excessive back pressure, due to a failed comb inside the catalytic converter, or there may be some sort of sensor malfunction, as well. In any Case, you will need to have the ECU(engine computer) scanned for trouble codes. Once the codes are pulled, you will be able to isolate the actual culprit for repair.

I suspect a failed injector of a malfunctioning ignition coil. Auto zone will run the scan for free. Kindly return with the codes for further repair info, if needed.

Loss of power until RPM gets above 2500

Hi Martin, As your vehicle is fitted with a distributer, try resetting the ignition timing. I believe it requires setting with a strobe and it should be idling at 750 rpm (manual box). I'm not expecting a drastic improvement with that action, because I'm suspecting that maybe the engine has been overheated at some time or another and you may need a cylinder head job carried out. I'm suspecting a blown gasket between cylinders. The higher the rpm the less leakage and the greater the power output. That would explain the lack of power up to 2500 rpm Regards John

My 1976 280z makes a poping sound between 1000 and 2500 rpm,but run smooyh above 2500 rpm

This sounds like a lean backfire due to lack of fuel response from you VANE air flow sensor, I have had good success recalibrating the spring the controls movement of the air door in the VAF sensor. This is a clockspring and can be set a couple of clicks tighter or looser to improve fuel response.

I just replaced the cable to my IMRC box on my 97 Mercury Sable and it engages as soon as I turn on the car or when I rev the motor above 2500 rpm. What could have done wrong or didn't do when I put it...

intake manifold runner control has linkage about 3 inches long and is attached to the end of the manifold. never knew of one with a cable. but the box is suppose to move the linkage with the key on to run a check on the engine and it is suppose to open the intake runners at and above 2500 rpm's to induct more air onto the intake at heavy acceleration.

My 1999 Silverado 5.3L automatic won't shift from 2nd to 3rd until 2500 rpm when it's cold. When warm works fine but 1st to 2nd shift won't happen until 2500 rpm, speratically. Transmissio

I had a friend that had this problem.I work at a G.M.dealership and I ask a friend that does trans work there.He said this is normal in cold weather.This is done in order for the trans to reach operating temperature sooner.This could be why you are unable to fix this problem because it is normal.I looked in service info to see if I could find a bulletin or something to back this up but I did not find anything.I know this guy very well and I know he knows his work and is good at it.Hope this helps.Good luck.
