Check engine light is on intermittenly during driving

Hi, Engine light is intermittently on and my car is vibrating when I stop at traffic lights. Car is opposing me to drive more thatn 60mph. Is it something to do with timing belt?. One week back, I had my car inspected with hyundai and they told me that engine is perfect.After driving just 15 miles, my engine light is back on. I own 2003 hyundai sonata(73000 miles). Recently changed timing belt, brakes, tires. Has any one come across this problem?

Well, My engine light came on. I have an 03 4 cylinder sonata and we changed ignition coils, my car vibrates and was hesitating. disconnected battery to reset engine light/computer, and today my car died on me while going down the road. it starts and kills. and when it does run it sputters. i say most hyundais have similar probs.

Well to tell you the truth with so many sensors you need to put the car on a scanner to fix the problem.You dont want to be changing part after part and not fix it,can get expensive.Get it scanned pay 40 to 70 dllrs get a report and you can change the part.But open you hood and look around it can even be a vacum line.Good luck.I can guide you thru changing the part.

Hi my 2006 3.2 blows puffs of un-burnt diesel smoke intermittently after it has been driven in traffic


have the variable vanes in the turbo checked for correct operation
there is an actuator that is vacuum
electrical sensor controlled and the vanes may be sticking at slow engine operations as on traffic
the smoke color indicates incorrect air/fuel ratio and the turbo is a point to investigate

Engine improper idle and vibration during stop and go traffic light


Hi and welcome to FixYa!

Looks like that you have a faulty MAF (mass air flow) sensor. If the MAF is faulty, erratic idle can be expected and shaking usually occurs. The MAF is located on the throttle body and replacement will surely be helpful.

Have a good one and thank you for using FixYa!
