I had a similar problem with a Grand Am one time. My check engine light would come on until I removed the gas cap and replaced it, after a couple minutes driving the light would come back on. My problem was a faulty gas cap. I would suggest taking it to the auto parts store and having them check the error code for you. Most will do this for free and point you in the right direction.

I have a 2002 doge caravan that i smell gas sometimes. its running rough and sounds its back firing. when you excelerate it doesnt want to and i hear a popping sound. already changed spark plugs and g


Remove the Engine Air Filter Housing and look under it for a vacuum line that goes back to the gas tank You will get a gas smell at times because this is an open line to the gas tank and evaporation container. It's common for the rubber elbow there to split and cause issues. Check ALL vacuum lines. The increase in air into the fuel system is causing a backfire "popping sound" and a loss of power.

Tip

Gas Cap Loose Service Engine Soon Light On


This can happen if the gas cap is not properly installed. Make sure you hear several clicks when installing. After 10 or so starts the Service Engine Soon light usually goes away.

A second cause could be a problem with the ground wire that comes from the gas cap sensor and goes to the body. Look up into the wheel well by the filler pipe to check.

A third can be the result of a vacuum leak in the fuel evaporator (EVAP) system. Look for any hoses that go from the air intake to a sensor on the fuel rail (fuel injected cars). Many cars have plastic engine covers that have to be removed to see the fuel rails, sensors and hoses. Most require unscrewing the oil filler to get the cover off. You may not think the hose is leaking but replacing may make your problem go away. A small vacuum leak can also affect the fuel flow and affect the engine operation.

My experience is with the 3.8 engine but this probably applies to lots of engines. On the 3.8 it is the two piece hose that comes from the air intake with one small hose going to the top of the engine and the other going across the front of the engine into a hose that does a 180 degree turn that comes back to a sensor. It costs about $25 and is a dealer item.

There may be other causes but these are three common ones.

The dinging from the dash is the Air bag system check. Check that the bulb in the dash isn't burned out. The stalling and spitting could be clogged converter. Check how much exhaust is coming out of the tail pipe when you rev it. The smoke could just be from a leaking valve cover gasket.

I'm getting gascap error and check engine light. What's causing the issue?


If you allready checked the gas cap and its on right.
Try replacing the gas cap with a new one.
You should here air wen you open the gas cap after driving
This is part of the emision controls and if it dosn't seal it will cause the check engine light to come on .

Check engine light cam on after i got gas


If you take this car for a scan the result will be an emission problem.

This simply indicates that the gas tank cover is not well tightened or the gas tank-cover has worn-out. But ideally, you need to just open the gas tank cover and re-tighten it.

I hope this helps out.

Thanks for using Fixya.

This is hard to describe, and is a multi-part problem on my 2006 explorer....first, here are the symtoms: 1.) heater blows cold air, unless engine is reved up...as soon as I let off gas, or am coasting,...


you have a massive vacuum leak, thats why your heater is not working fine, it uses a vacuum operated valve to transfer the hot water from the engine inside the heater core, and there is a door kind ventilation valve that also opens to make the air pass true the hot side, the sound you hear "blower like" its the air leak in the engine probably a vacuum line our broken hose check all the hoses there is your problem

The check engine light also monitors the deairate system of the gas tank. On the undercarriage (below the drivers seat) are 2 rubber tubes which get briddle over time check those for cracks. If you don't find any it is probably necessarry to empty the gas tank complety, make sure the engine is cold and pressurize the whole fuel system with smoke in order to find that leak.

A blinking air bag light might indicate a broken insulation on one of the wires of the wire harness wrapped around the steering column(inside a black plastic cover). To access it it would be necessarry to remove the steering wheel.
