Symptoms 2000 kia sportage Symptoms 2000 kia sportage does not do all the time. Starts runs well but driving road 50mph almost as if ignition shut off split 2nd. Stop car and while running in drive s


Some makers used Vacuum releases for their emergency brakes which had a Vacuum switch connected to the shift assembly. This would account for a stumble if Vacuum vented out through this switch.

More common for shifting stumble to occur from Park to Drive, engaging a load on the engine, not to stumble to a freewheeling Park position. Sounds like idle speed control is sluggish to stabilize the motor.

You also have idle speed control problem with A/C, kind of shows that A/C was what kept the engine running because when you turned the A/C off, the car died.

I am going to give you some Websites for wiring diagrams. Alldatadiy.com amd Autozone.com with free wiring info upon registering your vehicle.

It seems that the base Idle speed control is not working and the A/C idle speed control is.

Also check for Vacuum leaks on the intake manifold by spraying water from a pumpbottle on the seams of the gaskets.

Check ignition Relay or ignition switch for random cutouts. The fusebox layout is on the Autozone site.

I hope my solution helps.

2000 pontiac grand am 3.4 motor auto trans 4 door.Car starts and drives okay motor seems to stumble slightly between 3000-4000 rpms. with car stopped in park try to rev motor will only go between 3200-4000...


Hi Tom your vehicle is equipped with a Rev limiter it will not allow you to rev the engine above 4000 with the trans in park; as for the first problem you may have one of two things, one of the spark plugs or spark plug wires is bad or you have a flat spot on the throttle positioning sensor in which case have be replaced. Good luck?

I have the same problem on a s320 cdi, gearbox goes into limp mode and wont rev above or kickdown, at the 1st chance i get to stop i put into park or neutral gear turn off the engine and re-start and then everthing is fine, I read that if you put a new battery on it may solve the problem, it's something to do with the voltage dropping below 10.4 volts. Then it sends a message to e.c.u. that puts your gearbox into limp mode. Hope this will work for you. MERKY
