check the wire harness that connects to the engine block, on the back
If a check engine light is flashing that means an engine cylinder misfire has been detected
your sunfire is revving if the idle is set to high, or when adjusted. the idle is high also when the engine needs to warm up in cold weather. there is also the possibility that the engine temp sensor needs to be replaced, for it is not relaying proper heat temp. the light on your dash may show you engine temp, check this. if unable to do this yourself, you may need your cars manual.
cant you need a scanner to check codes from 1996 and newer
95 s10 blazer has a miss and check engine light does not come on and exhaust smells gassy what could it be
Most likely they are engine mounts. As for the loud engine, check the exhaust.
Could be a restriction in the exhaust such as a catalytic converter that has had a meltdown. If the check engine light is or has illuminated, check the codes.
Or someone didn't do a proper job on the repacement engine and you've got a leaky head gasket.Answer"Stuff" is still in the muffler and exhaust system.Thick white smoke can also be the transmission oil being sucked to the engine. check your transmission oil as well.
The check engine light comes on when the computer detects a problem and sets a code. You need to have it diagnosed with a scan tool. The loudness may be an exhaust leak. the o2 sensors will pick up the change of exhaust gases and set the Check engine light.
Check engine light (usually), sulpher/egg smell from exhaust, severly decreased fuel economy, sooty exhaust/tailpipe Check engine light (usually), sulpher/egg smell from exhaust, severly decreased fuel economy, sooty exhaust/tailpipe
I would check the plug wires and the exhaust system.
The check engine light in a 2004 Toyota Tacoma can come on for many reasons. It could indicate an exhaust leak or a problem with the engine.
Faulty catalytic converter, or sensors in exhaust faulty
It means that your relay is out, and has to be replaced with a new one, and once its been replaced, your check engine light will turn off in about 20 minutes or so.
Need to check fuel pressure with a gauge Check the exhaust converter, and exhaust and make sure its not restricked. Engine vaccume should be 18-21 inches of vaccume. check it with a gauge. need to know what year it is.
Check your fluid level in your cooling system. Run the engine and check the fluid level after several minutes to see if in fact it is your coolant entering the exhaust system. If this is the case your engine block could be cracked and might have to be replaced.
it probably needs an O2 sensor they range from about 40-90 dollars
bleed the brakes. check fluid level
There could be several reasons why a 1996 Sunfire will turn over but not start. The most common reason is a spark plug needs to be replaced. Check with a licensed mechanic for further help.
check engine light reset on a 1999 acura cl 3.0.. Just replaced the egr valve. Thx
Water is in your engine. Check intake and head gaskets.
the check engine light means you have something wrong with your emissions. it might be the two sensers on the exhaust pipe.
