Hi there. This can be caused by a number of things. If it only occurs when accelerating then I would check the fuel pressure first. If the fuel filter is old or clogged then this will occur. It can also...
It's not really likely that the timing is off. Modern cars with distributorless ignition rarely have any issues with the timing. If you're having problems with your idle the first thing to look for is air leaks. Any air that...
Hello. I would start by scanning the vehicle for codes and checking to see if all of the sensors are reading correctly. If everything looks good then chances are it needs a new computer. I have seen the computers fail...
Hello. Though there are a lot of things that can cause this typically it is due to an issue with a failure in a spark plug or an ignition coil failure. If there is not a check engine light on...
Hello. From what you are saying I do not think that you had a fuel pump issue to begin with. This engine has a history of vacuum leaks that can form or valve timing solenoids that can fail. These are...

Hello. I have seen this frequently on this vehicle. Most of the time the issue is with the crank position sensor. This sensor tells the computer that the engine is rotating. If it fails the engine stops. These will go...
Hello. It is very hard to properly diagnose something without driving the vehicle and fully testing it. You will more than likely need to pay for a diagnosis to know for sure what is going on. From my experience though...
Hi there. Though there are a lot of reasons that will cause this most of the time on this vehicle it is due to a failing crank or cam sensor. both are common failures. I usually start by scanning the...
Hi there. It sounds like you either have some sort of vacuum leak or possibly an engine misfire. I usually start by checking to see if the check engine light is on and if it is then I scan the...
Hello. There are a lot of things that can cause this. If vehicle was having trouble getting to that speed then it may be a transmission issue or it can be something like a catalytic converter that is failing. If...
Hello. There are few things that I recommend you have a technician inspect. In order of probability your vehicle may have a bad mass air flow sensor, a bad crank position sensor, a bad throttle position sensor, or restricted fuel...
Hello - it would be useful to know what the "successful" dealer did that improved the hard starting problem. These problems may or may not be related. What is the behavior when it shuts off? Can you start it right...
