Check engine light after an oil change?

I had my truck serviced at jiffylube, got the full service and afterward my check engine light came on. I took it back, advised it had NOT done that until they worked on my car. They spent an hour looking at it (left their cordless phone under the hood) and had no idea why this happened. They finally gave up. I spoke to a mechanic who advised the may have knocked a wire loose. The only wire I can see if a blue whire that runs from one of the battery posts to a fuse and then on to what appears to be a group of wires bundled together. Any idea what the blue wire is?

Took the minivan in for a power steering flush. One day later there is a whiny noise when the car is running and a loud groaning noise when I an turning. The noises were not there before. baffled?

You have air in the power steering fluid. Check first to see that the reservoir is at the correct level, and add some if necessary. Other than that, if there are no leaks, the air will eventually work its way out of the system. You may want to sit with the engine idling and just run the steering wheel from full left to full right and back a few times to expedite the process (don't hold the wheel at the full lock position though). By the way, who did this for you? Jiffylube, or one of the other 'service' establishments with unqualified mechanics?

I just got my 2003 Cadillac deville..any everything was great..about a week after I got the car I took it Thur the car wash and out the blue the service engine light came on...what can that possibly...

A service engine light means it's time for an oil change. That light needs reset after the oil is changed. The computer senses the miles drove automatically and says "change my oil, it's been 3,000 miles" A CHECK engine light means it has to get a scan done. Change the oil, it will be fine. It is suppose to do that. Let me know if this helps you.

When I turn the key on there are there warning beeps on my 1988 audi and the oil light comes on whats going.

If the oil's full the problem is in the sensor and a mechanic can repair the problem. If the oil level is low, change or fill the oil and the light should go off. If you've never done an oil change yourself you may want to have assistance as it can be tricky. When you check the oil and the level is at the "add" line you will add one (1) quart of oil only. If it's not registering on the dipstick you'll need to add two (2) quarts, check the level after several minutes and add accordingly. JiffyLube does good work and will save you the headache of labor. Good luck to you

The car stalls after turning over

Whenever the 'CHECK ENGINE' (Service Engine Soon) light comes on, the ECU (Engine Control Unit) sets a Diagnostic Trouble Code (DTC). These codes identify the particular engine management system which caused the light to come on.
You'll need to use/find an OBDII (On-Board Diagnostic) Scanner to retrieve any code which have been stored in the ECU computer. Afterward, we might be able to help you DIAGNOSE the problem and perhaps eventually fix the problem.
Go to and register( Vehicle by VIN). Afterward, you have access to shop manuals, service bulletins, wiring diagrams, etc. about your vehicle.Take/Tow your vehicle to an authorized Hyundai dealership and pay the diagnostic fee... they will tell you exactly what the problem is and the cost of parts/labor to fix it... at least this way you'll know what the problem is and what's required to fix it.

Flickering oil lights

Does the oil light flicker only when the engine is 'idling'? Or does it flicker ALL the time? Does it flicker when the engine is cold? Or, only after the engine warms up? Cause could be low oil pressure (check oil level & condition- should be full and clean), could be the oil pressure sending unit going bad, could be electrical (short) in the oil pressure sending unit wire harness, could be sludge buildup in the crankcase clogging the oil pickup tube to the oil pump, or it could be a clogged oil filter or the oil pump is going bad. If you have an after-market oil filter installed, they somtimes rob the system of pressure. There is a Technical Service Bulletin on this for Hyundai Vehicles. You should use the genuine Hyundai Oil filter.
Does the Check Engine light come ON when this happens? Whenever the "Check Engine" light comes on, there is always a DTC (Diagnostic Trouble Code) stored in the ECM (Engine Control Module). You'll need an OBDII (On-Board-Diagnostics) scanner to retrieve any codes recorded/set in ECM. Once you do this and let us know what, if any codes are set, then we can go from there. OR, take/tow the vehicle into a Hyundai Service Center (dealership), pay the diagnostic fee. They will tell you EXACTLY what the problem is and what's needed to fix it (parts, labor, tax, time-frame, etc.). You could also go to and register (vehicle by VIN). Afterward, you'll have access to technical information (manuals, wiring diagrams, service bulletins, etc) about your vehicle.
