I have a 2001 VW jetta (130,000 miles) and recently went to Midas to have my brake pads & rotors replaced. I have had a problem with the CEL coming on after I lost my gas cap. I replaced it twice and w/ a genuine VW cap....the light went out for a short time and came back on. I took my VW to a local garage and the tech thought that I had a small leak in the air intake tube for my gas line? He coated it w/ silicone to see if that would take care of the problem and the CEL was out for months. But,

I have a 2000 Pontiac Grand AM SE with a V6 3.4 liter engine. I had my check engine light come on and went to Auto Zone to get a code which related to a emission vapor leak. So I took car to my mechanic and he performed a smoke test which indicated the vent solinoid was bad. Had him replace it, hooked up scan tool to turn check engine light out then a week later came back on indicating same code. So my mechanic suggested to replace gas cap and purge valve because thats all it can be. Did that an

I had blinking vsc code and check engin light on. Took it to a dealer who ran diagnotic. Dealer said gas cap has failed and new charcoal canister is needed. Since the high cost of latter, I simply replaced gas cap only and warning lights remained off. now, 4 months later lights came back on. Am I going to have to replace gas caps every couple of months? If I buy a new cap and put it on myself does the warning lights go off by themselves it this is the correct fix or do they need to be rese

2004 GMC Envoy, My service engine soon light came on. I took the vehicle to a mechanic and the code came back po422. A smoke check was performed and they said it had a leak in the filler neck and the entire gas tank needed to be replaced. So the dealer replaced the tank and now I'm getting a loose gas cap message light on the dash. Since the dealer did not replace the cap when replacing the tank is that what the problem is, or was it not the gas tank issue at all?
Hello: Without being there when the smoke test was performed no one can say what the results of the smoke test were. I would go back to the dealer and speak to the service director/service manager and request a new gas cap. ... 2004 GMC Envoy

If they forgot to tighten the hose clamps on the hose from the tank to the filler cap it could be setting it off. If they are all tight it was probably just the gas cap. The gas cap is usually ALWAYS the culprit. Let me know if this helps ... 2004 GMC Envoy

On my 2003 dodge caravan the check engine light is on. Took it to a machanic and he replaced the gas cap. 4 days later it came on again. He then replace the o-ring around the gas cap and checked all the emissions hoses. The code says its a emmissions leake. Machanic still cant figure it out. Can anyone help

I have a 2004 Jaguar evap control system leak, codes P0445 nd Po447. I have replaced the Gas cap, but light keeps coming on. my Actron tester can send a command to test the evap system,but I don't know what to do when it is in test mode, am I supposed to wait for a code?

Replaced Bank 1-Sensor 1, check engine light came back on, now I'm getting 10 mpg, black smoke when I get on it.

My check engine light in my 2003 Kia Rio keeps coming on. So far, my mechanic has pulled codes for and repaired the following. A flex hose pipe, the 02 sensor, pin holes in the exhaust, the gas tank and the purge solenoid. I am trying to get the vehicle inspected, but we can't seem to find the problem. The code that keeps coming up is an evac or exhaust leak. Yesterday, after replacing the purge solenoid, I didn't even get it home, about 10 miles away, and the light came back on. Any tips

I have the code P0455 and P0442. I replaced the gas cap with a new cap and had a mechanic look underneath to see if their were any hoses off or leaks and he couldn't find any problem. Could it be a valve problem in the rear by the tank? He cleared the codes and I drove it a couple of days and the check engine light came back on.
