Check engine light is on, possible wiring problem? HELP!?

First of all, when the check engine light is on, you have a problem with a emissions sensor. wiring problem is very rare to set off the check engine light. When they checked it, did they give you the fault code?? If you are able to get that fault code, that will be a start in the right direction to finding the problem

make sure you get the fault code print out from the person who pulled the code. Many people dont understand that autozone is mainly for the do it yourself customer so having them pull the codes for you and take a wild guess at what the heck it means doesnt help you. Pulling that engine code is only the first step to diagnosing your car. Just take it to a respectable a shop and have your car checked out the right way because If you dont know how to actually fix it P0300 means nothing to you lol.

you're able to understand what the hot examine engine easy errors code is. it would desire to be a clean code or it would desire to be an ignition misfire code back like final time. once you're saying the motor vehicle did the comparable subject back, do you advise it particularly is surging and hesitating back or only that the yellow examine engine easy got here back on? If it particularly is surging and hesitating back, the keep will only try disconnecting and reconnecting the hot spark plug wires at the two ends, separately hoping it particularly is basically a bad connection. in case you get the codes examine out back, write them down and have them sparkling the codes. besides the fact that, a background of the code occurence will stay in the pc many circumstances till you force some weeks without the examine engine easy coming back on.

what was the check engine light on for? What was the code they gave you?

If the code referred to engine knock detected then it just may be the knock sensor is bad if have not heard any engine knocking. Replace the knock sensor and have the code cleared. See if it comes back

Time for A SHOP VISIT.
