Question about 2004 Suzuki Verona

1 Answer

Chevy check engine light

Check engine light is on, and the car is idling very rough and stalling at traffic light and stop signs, and when I back up. Check engine light has been on and off since last Fall, giving different codes every time it's checked, from cylinders misfire (#1 & 4) to O2 position censors to throttle position sensor. Could all these codes be related to the current stalling problem?

    Just had a comprehensive diagnostic done at the dealer. They charged me $145.00 for it. They got the following trouble codes: P0102 MAF Sensor circuit voltage low. P0121 TPS Performance, P0171 fuel trim system lean B1, P0304 misfire #4 cylinder. Dealership quotes me $1500 to replace leaking valve cover gasket, all new spark plugs and 5 new coil packs (spark plugs and coil packs were all replaced in Sept. 2012.) The car is only worth $3,000. This is ridiculous. Any suggestions would be welcome

SOURCE: I have a 1.8 1998 suzuki sport sidekick jlx. It

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.

Engine malfunction light on all time drives ok but when stop at traffic lights etc ref counters go down and stalls

IAC problem . You have a problem with you idle air control valve. So when you stop at a stop sign the RPM goes to low and you stall out. IAC controls the desired speed necessary to keep the engine running.where is this sensor at is at the rear of the engine compartment under the thtottle valve. Here is what you need to inspect for. If you have a vacuum leak in you engine system, the IAC cannot compensate or control and you get rough idle. Check any loose vacuum connections .

My 2004 Expedition 4.6 ltr. has a rough idle. It goes Up and down and will stall at stop signs and traffic lights. Where can I find the PCV valve?

PCV has nothing to do with drivability or any thing else pertaining to engine performance. It regulates the air flow out of the crankcase to burn blowby gases from the rings. It never needs to be replaced,just cleaned every four years. That is if you have no hose leaks.

Buy some CRC Throttle Body Cleaner and follow instuctions.
I wouldn't even run engine,just spray and clean throttle plate.
Plate is sticking open and throwing TPS Voltage off at idle. PCM is trying to figure injector pulse, with wrong info,thus rough idle.

Car ideling roughly ...not stalling

sounds like you may have a problem with your Idle air control valve, located on the throttle body. this is what controls the idle when coming to a stop or stopped and turning corners or basically when your foot is not on the gas pedal

Rough idle

I had the same exact problem on my 2004 Colorado (3.5L). Cleaned the MAF sensor (with MAF sensor cleaner) and throttle body/plate - cleared it right up.
