Question:

Why wont my engine light turn off after I fixed what auto zone said to fix?

About three weeks ago my engine light came on in my car and I‘d never had anything for wrong with it in the few years I had it. I took it to auto zone and they ran a test that came up saying that my gas cap was defective. It wasn‘t loose because it had be on both prior to and after filling up my car. They gave me a new gas cap and said to drive around for a while and the light would turn off on its own. Well it has been three weeks and my light is still on. What‘s wrong?

Answer:

Maybe a polystyrene foam as used on some industrial tires, bicycle tires? Won't go flat, doesn't ride good at much over 15 mph but will hold some with splits, give some rebound. I had some put in bicycle tire, worked- but not good for motorcycle on hiway. Dirt bikes sometimes had extra thick innner tube and Slime or flat Pruf filling between tire and inner tube, low pressure for dirt grip and safe enough for 30 to 45 mph even with some sidewall damage. Emergency use only - Radial tire patch on side wall damage from inside, inner tube with double layer and sealer as used on some dirt bikes or extra liner over inner tube- can get a 4x19 side wall damaged tire on Triumph home 200 plus miles at 50 mph top. what is actual motorcycle? how fast will you be riding? Your post implies you did get the emergency filling and are currently riding it for next month as shop noted would be about all they could hope for before they sold you new tire. Ice racers, some desert drag racers will have a smooth tread secondary tire/'liner' in some tire with studs in outer regular tire- this will help with side wall damage tires, is used some on agricultural equipment, industrial equipment that has hazardous ground with lots of cutting , scrap metal, thorns to worry about. Fiber and foam filling used sometimes as well - not recommended for high speed- but 30mph on some wagons, implements done. Ask the shop that did the work what they used.
I have a 2001 Pontiac Grand Prix GT (same engine). When you put the gas cap back on after filling it up, are you tightening it enough to make it click at least 3 times? If not, that could be your problem. If you do that and it still doesn't go away, take it to a repair shop for an estimate -- NOT a dealer. Dealers will charge you top-dollar and do piss-poor work. The last emissions control problem I had was a bad EGR valve, and that cost me about $350.00 to get it replaced.

First off, never take your car to one of these fast code reading type places. They sell you things that you don't need because they lack the knowledge to fix them properly. If anything, just get the code from them and check it out for yourself. Or better yet take it to a qualified repair shop that has a good reputation for diagnostics. The code that the light was on for was probably an evap leak. Although a defective gas cap could be the culprit, it is very unlikely. That system has many hoses that run from the back of the car (at the tank) all the way to the engine. Also there are a few valves and solenoids that could be bad. What I'm saying is this specific problem has to go through a bunch of tests before anything can be condemned. So for AZ to read the code and just say you need a gas cap and the fact it was tight leads me to believe they just sold you something you most likely did not need. EDIT- Giving AZ the benifit of the doubt, lets say the gas cap was the problem. Driving the car will eventually turn the light off. Each code has a set number of pass tests that it has to go through before turning the light off. The evap system, the system involved in the gas cap, would take a long time to turn it off.
That tire is shot. You can't fix sidewall damage like that. Any bodge patch will leave you rubber side up/dead. Find a new shop. I would never, ever step in there again.
