Question about 2000 Toyota Celica

1 Answer

When at a stand still car idles evenly although maybe a bit high (1000rpm), if i was to stop on the top of a hill then just free wheel down out of gear then the rpm's fluctuate between 1000 and 1500 rpm but as soon as i come to a stand still they settle again. A performance exhaust was recently fitted, could this be causing some kind of problem ?

Yes. The engine relies on the right amount of back pressure from the exhaust system. If not enough,usually aroung 1.5 psi, then it can cause engine concerns.Check for any and all vaccum leaks first before condeming the exhaust system. Use your ear to locate any large leaks and you can use water to locate any smaller leaks. Listen for a hissing type sound.Check for broken or missing vaccum lines also.The water will be sucked into the engine causing it to decrease the rpm.The idle air control valve would be another part that will cause this concern,but not likely on this vehicle.Hope this helps,
Ken

Why does my 255 massey wants to free wheel down a hill


check that the gear box is not jumping out of gear when over driven. That the ratio box is not disengaging ( high /low gear lever). IN some instances when you stand on the brakes it will automatically disengage the pto so check the positioning of the brakes .

High idle benz 190e


Could be a defect in the ECU. But 1000rpm is not that high my cars normal is 1000rpm. but some older models were about 700rpm
The AC rise is normal. You may want to have a OBD II check by your garage or you can buy a unit to do this. It will scan the sensors fitted for any problems.

Very possibly a vacuum issue. Maybe a line that needs vacuum for the trans is on an inlet that effects the throttle. Not sure how old your vehicle is.

@1000rpm car idles good, under 1000rpm,engine has rough idle, even cuts off at stop light or stop sign


you may want to check your Idle Control Solenoid Valve if it needs cleaning. This is a common issue. If this does not help, I would ask for more details like maker and engine model.

Toyota estima 2.2 td 1992 water temperature high


I had same problem, but when I got to top of hill and sat idle for a bit, it would kick down ? replaced thermostat and still happened until I dumped radiator fix for temperature problems, overheating and such and has not happened since, no problems but even when I know the engine has to be overworked and should show hot, it never goes past middle. I'm not sure of name of liquid, got it from a car dealer, but it is basic about $18.

Hesitation or stumble during acceleration


take your car for a tune up
if they are carburetor type motors you may need your carbie cleaned and a tune up
if you clean it your self with carbie cleaner it may increase in idle speed this is nothing to worries about it is a simple adjustment
with a carburetor type motor they tend to idle higher when their cold this is the automatic choke kicking in and normally it should happen till the car is a bit warmer and the accelerator has been depresses
although a car should idle at 800 rpm my paddok car dose when it is cold it idles at 1200rpm i like it this way as the car warms up quicker as i will not drive a car while it is cold
hope this helps

High idle with a/c on.


Cars are SUPPOSE to idle higher when the A/C is on...(especially 134a systems)..the idle will go up and down as the compressor cycles on and off.
