I got it to run and not die. You must use throttle to get it to start and warm up. Then when you release the throttle it will drop to 200 rpm and slowly come up to 800. It has 4 codes. 1st to last - p1701, p0725, p0705 & p0500.
the car just started running hot tonight
Problem first started driving down the road, lights and gauges started going crazy. Replaced the alternator, couple days later it started again, replaced the battery, few days later I'm outside and hear the car trying to start itself, with nobody in it, no key in it. It must have been doing this for a while, drained my new battery. What could be the problem? I'm thinking ignition switch?
My heat doesn't work because my ac light doesnt turn off. How Wilk Ibe Able To Turn My Ac Light Off?
My brake light stays on and drain my battery this starting happening 2weeks ago. I recently had my oxygen sensory replace.
When I go to fill my car with gas, the fuel nozzle keeps cutting off the flow of gas. ( Like it's tank is full) I saw a service bulletin from another make of car,suggesting the problem is with a vapor tube that goes from the gas tank to an evaporative emission canister. B4 I lower the gas tank, is this reasonable thing to fix my problem?
Where is the fuel relay switch located I looked under the dash but did not see it there, is it on the fuel delivery assembly in the tank?
At stops it idles a little rough.takes off slow..what could it be...every time I drive it but this just started...use to run good no problems before
changed alt and battery. and I am getting no charge coming from altenator.
THe problems that I am experiencing include: bad gas mileage, hesitation during acceleration,and constant misfires. Hesitation occurs everytime I try to accelerate and it takes about 15 seconds to get up to 70 MPH. It has also started to have issues starting.
and also my rear window defogger stopped working. Had problems in the passed with the indicator light when it rained but it always came back to normal when it dried out. This time that's not happening. Took a test on the alternator and found that it is not charging at all, But can an alternator cause all of these problems? I can see the alternator light coming on due to the bad alternator, but the break light and rear window defroster problem has me confused!!! Thank you in advance, Pete
need to replace radiator and need an estimate
The gas pump clicks as if it is full, but it's not,so I squeezed the gas nozzle and gas started coming out as if it was full. Do I have a bad fuel sensor?
Its very sporadic may work several days then stop or come back on.I think its in the switch somewhere ,your opinion is welcome.
Do you think its a switch or the blower motor?

To add: A Door the back driver will not lock AUTOMATICALLY and radio also comes on when its actually turn off maybe after hitting a bump..
