The car is overheating but ck eng light not coming on. The transmission catches hard intermittently. The rpms seem to be running higher than normal.


check for low coolant level.check coolant overflow jug if it is empty, more likely air is in the coolant system.add more coolant to overflow jug until coolant level stay at cold full mark,dont over fill coolant overflow jug.if all is good, to be on the safe side, replace radiator cap,replace thermostat,if your engine overheat at a long slow driving traffic.or long stop idling, if cooling fan dont turn on more likely engine coolant temperature sensor could be faulty.

Chevy Malibu Cold Idle Problem


Check the water coolant thermostat. If it is stuck in the "open" position you are heating up all the water in the coolant system and this will take time. The thermostat keeps the water in the engine until warmed up to almost normal running temperature, only then does it allow the coolant to enter the radiator.

I have a 1.8 1998 suzuki sport sidekick jlx. It failed emission testing. Replaced the mass air flow sensor, throttle position sensor, coils and spark plugs. The check engine light still comes on and it...


hi,
spark plug wires, fuel filter, air filter, or fuel pump might be getting ready to go. maybe a vacuum leak, hook it up to a vacuum gauge and see if the needle is steady, or take it to autozone and have them run a OBD test. I think its free at autozone.

My 98 Honda Accord Vtec 4cyl. eng is starting fine, but after start the idle dips a few times and regains for approx. 3min. If I drive without warming up the car will hesitate and the gas pedal will delay...


Seems like the coolant temperature sensor is giving the computer erroneous readings, and it is not adjusting the fuel mixture properly for cold engine operations. You should have the check engine light on, indicating this malfunction. The idle fluctuations are normal. The engine is trying to die, from the improper cold mixture, and the computer (ECM), recognizing low idle speed, is sending it back up. Another possibilty is that the butterfly on the throttle body is not closing completely, to allow richer mixture needed for cold starts.

Runs ok cold. looses power at low rpms and sets


This because when wires get warm they change shape and this means that your coil isnt getting good contact somewhere. I would replace the coil.

If the engine seems to run fine over 1450 RPM maybe there is a vacuum hose leaking or EGR valve is slightly stuck open. Any help from the OBD II trouble codes? Or is there simply no MIL and no stored information in the OBD II computer read at the local parts store through the connector by the drivers knee?

Not reving high on cold start


Here is the most common cause of surges and stalls and low idle, it is the idle speed control air-bypass valve and throttle valve (IAC for short), they get full of gunk over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake
