    Car accelerates without my foot touching the gas. Even when the brake is applied.

1999 gmc suburban-smoke comes out exhaust and smells like gasoline


If the check engine light is not on, I would check the fuel pressure regulator and for problems with the fuel return line.
If you have a leaking injector you should get a check engine light and code for a cylinder miss.

My 2004 Hyundai Elantra surges and jumps gears


You got ripped off by the mechanic. A good mechanic can pinpoint the problem by using a scan tool. Take vehicle to autozone or similar and have it scanned for codes this will give you a idea what is wrong. I believe the problem is exhaust related because of the blinking light.

Cabin smells when heat or defroster is on


What your smelling is most likely coolant (antifreeze). You may have a heater core leak. If you dont smell the same smell after running the A/C or just vented cool air from outside for a few minutes then that is your problem.

Engine light on--exhaust smell in car--just replaced engine


the ac is a gas leakage problem and can be fixed by an accredited ac specialist shop
the exhaust gas smell could be the flex pipe at the exhaust manifold or a exhaust pipe gasket that has failed ( come loose after the engine replacement)
as for the engine lights , it con=mes on from reports from the engine and the transmission so have the fault codes read to find which sensor is reporting a fault
could be that same sensor that reports on the exhaust problem
hard to start is an electronic reporting fault and that will be in the codes as well

Check engine light on in 93 Lexus


The only way to check why the check engine light is on is to have autozone or a mechanic put a scanner on the car and read the engine codes. This will tell you exactly what is wrong. Many part stores will test it for free. Mechanics will charge about $40 But you will definately know exactly what the problem is.

If gauge is fine and car smells hot. It is probably due to plugged exhaust unless you have a wire laying on the exhaust manifold and it's melting.

2005 nissan murano "s" surges and bucks when accelerating.


You need to have your engine flushed and cleaned out. One or more of your spark plugs aint firing. You need to replace them all to include the wires as well. If you dont get your engine flushed, you could blow your engine up.
