Might need a new IAC, idle air control. If it is stuck open it can cause a high idle condition. Or you could have a vacuum leak. Is there a suction/whistle kind of Sound from the engine compartment that sounds new?

Any job can be done at home provided you or your mechanic friend has the proper tools and understanding to perform the job. If you're a beginning do it yourselfer or just need a refresher I would highly advise getting yourself a service manual for your vehicle at your local auto parts store. It will have decent instructions and pictures in performing most of the jobs you may encounter for your vehicle. Also you may want to take pictures or make notes before anyone removes any components or lines in order to remove your intake. If you need any help with this procedure let me know and good luck

Hi Everyone, Hopefully this will help someone. My 2002 Malibu, 3.1L V6 has been running hot in the afternoon summers here in AZ. Once it got close to the red line which really was unnerving. Immediately I turned the heater on (to use its radiator) to help cool the engine. Lately it has been running about about 3/4 of the Temp Gauge - over 220. YIKES!!! So, I did this..... Open the FUSE / RELAY COVER SCREW (located in the black box next to the brake reservoir. NOTE - BRING A MAGNIFYING GLASS TO USE - THE PRINT ON THE BACK OF THE FUSE/RELAY COVER IS EVERY HARD TO READ) **** Check FUSE 55 - COOL FAN #2 - GRND 30 A **** CHECK FUSE 52 - COOL FAN #2 - 15 A **** CHECK FUSE 8 - COOL FAN #1 - 30 A ALSO go ahead swap four relays - Make sure there is no corrosion (Mine DID have a little) and Clean it up good. SWAP (SWITCH ONE FOR ANOTHER) THE TWO 7234 - RELAYS -- #15 - COOLFAN MODE & #13 ALSO SWAP THE SWAP (SWITCH) the 7236 RELAYS. In my case it was the Fuse 52 - Cool Fan #2 - WHAT A RELIEF!!! BEST WISHES TO YOU ALL !!!! Scott

It certainly is, and could be caused by a lot of things that are not necessarily related (such as blown fuses, faulty switches, connector problems). However, with speakers cutting out, you could have a serious wiring harness problem inside the car that is affecting all these systems. I suggest you get all of these checked out by a shop to avoid possible serious trouble.

Sounds very much like you have a nick on the wiring and it maybe shorted, check your Fuses, it maybe a fuse, but if it's a nick in the wiring shorting, get it to a Garage to check, as it may cause a fire in the engine someday.

would be worth having the cat converter check for blocking the exhaust system

Whistle noise indicates a major vacuum leak. Maybe something loose in the intake system. Maybe a vacuum hose disconnected. Will explain lose of power also.

You are getting oil in the cylinder and that is fouling your plugs. I would guess your piston rings are bad letting oil up into the combustion chamber or it is leaking down from the head through the valve guides. Good luck

I hear you say missing.. Have coil pack, wires, and cam sensor , (timing) checked. seems the timing is being affected under load.

2002 Chevrolet... • Answered on Sep 19, 2017

Check with the auto parts store to see what the fuel sensor looks like, It should be accessible and I have seen those go on the smaller chevys like aveo. Look up on internet replacing gas recirculation sensor on google

I agree with Andrew about the battery and connections. If the battery is down, we're just spinning our wheels. You need to get it charged up. My info says you have passlock security system, the majority of these systems are fuel injector disable, only. I looked at your starter wiring circuit, if my wiring diagram is correct, your security system has no control over starter motor circuit. With passlock, it is the key cylinder that is matched to the security system, not the key. The key is just a mechanical key.
