SOURCE: colt idle problem.

Most likely you have a bad Idle motor which is a small motor mounted on the intake manifold. If the motor can run better with your foot on the gas but dies if removed then it is probably this. This motor is controlled by the OBDII computer which gets it's control signal from the temp sensor which is located either on the radiator or engine block (which could also be bad), if the electric fan (if equipped) turns on then this is not the problem part, but the idle motor is. Another possibility is that you have some bad /cracked vacuum hoses which should be checked for first, before replacing the idle motor.

Probably a short or loose connection between battery and starter motor, or on either end of cables. Id look there before swapping out starter.On cold days you might put a heater under car for a few hours before using it,do this carefully as to avoid a car fire, or look into a block heater for your engine.

SOURCE: subaru impreza 2l turbo, 1994, starts fine and

Hi there i had the very same problem on my 98 impreza 2l turbo, this was caused when i removed one of the catalytic converters from the exhaust, i was hitting the 'fuel cut off' because i had increased flow through the exhaust causing the boost pressure to rise quicker and higher. this happens at 18.8psi of boost pressure, i had to get mine taken to a rolling road to be fixed but touch wood have ad no problems since, hope this helps.

93 subaru imprez.when warms up it starts


Sounds like it's getting too much fuel because is still in cold start mode by computer. This is because of a faulty heat sensor. Once the heat sensor tells the computer it's warm, it runs fine, IF the sensor is working. If not, the computer doesn't know any better than to keep it in cold start mode. I hope this makes sense to you.

2002 Sable sedan choke/missing/sputtering intermittent


The PO 316 is still misfires om first 1000 revolutions
so the shop did a poor job for you on resolveing the
cylinder misfires

Try a diffferent shop

Have to clean the MAF Sensor & replace upstream
oxygen sensors if over 100,000 miles

Need the correct oem spark spark plugs/any brand

No reason the gas filter should be clogged unless it was in
the car for 10 years

Fuel pressure should be checked

Need to check for cylinder misfires on a road test of 20
miles or more with professional software in Mode#06

I give it gas and it won't accelerate


Can be several problems, one the injectors can be clogged and not allowing the gas thru at a fat enough rate, two it could be a gas filter going bad.

Try changing the fuel filter sounds like your not getting enough fuel & if it is fuel injected I would try a fuel injector cleaner. Hope this helps to get you up and running.

give it a oil change and put a new fuel filter on it. you might have to change spark plugs and spark plug wires. also put some engine and fuel treatment. if that does not work put about 5 gallons of premium fuel in.
