SOURCE: when cold, it idles rough, revs high then low! After warmed up it runs fine

if it runs high when you first start it then mellows out,, theirs no problem , all of our chevys do that.... but if its sputtering or you hear a quiet popping noise check spark plugs

Replaced head gaskets on pontiac trans am 1997 lt1 eng now its over heating


trapped air. When temp needle climbs to 1/4 way, loosen coolant temp sensor to bleed off trapped air in cylinder heads. Air is gone once coolant starts to stream out, but only open slightly at a time. May have to do in increments as trapped air will cause rapid overheat

I have 2002 Isuzu trooper 4X4, on a dashboard 2 lights are on, Engine Check and CHECK TRANS blinking every 2 seconds. Car itself operates very well, shifts gears etc. when I drive around town it works...


Have you checked for Diagnostic Fault Codes yet? Have your local auto parts store check for codes if you don't have access to a code reader. New Bluetooth OBD readers (ELM327) that pairs with your smartphone or laptop and a free app. (Called "Torque") Great reader for under $20 in most cases. Start there first. Is there a Temp Gauge for coolant? If so.......what is the operating temp doing during those highway trips? If the coolant is overheating, it may be heating the transmission too.
1. Check for codes.
2. Have cooling system checked, cleaned, flushed, and new coolant installed.

Chevrolet Cavalier 2004 quits running while driving down the highway.


need to check fuel pressure, not just listen for pump to run, also check reading on coolant temp sensor, but sounds like fuel pump /filter issue. just because you hear pump run doesnt mean its putting our right amount of pressure. also check for plugged catylic convertor

Car only start with cold engine


This can actually be several things but most common is the coolant temp sensor, it tells the computer how much fuel to give the engine depending on temp, if the sensor goes bad then it may be giving engine too much fuel when it's warm, which may be why it starts fine cold cause it needs more fuel to start cold, try holding the gas pedal to the floor when u start it warm, if it does start and run rough for a few seconds it's cause it was flooded due to excessive fuel.. Get scanned for any trouble codes..

AC has freon but it quits and starts blowing hot air then it has a blue thermostat symbol on dash has 2 codes po 128 and po 118


Both codes are for the coolant temp, the blue symbol means the car is cold, check the fans to make sure there operating and check coolant level

Car does not want to start in cold weather, idles for 2 sec then quits this continues for about 10 to 15 min until engine gets warm then starts.


Sounds like you may have a bad coolant temp. sensor, scan your system for trouble codes, it may tell you, or just change it, at least you'll eliminate one possibility.
