Hello,

When driving at any speed and actively pressing on the throttle the car performs stellar. When I let off the throttle or keep the throttle at a steady speed, the car sporadically feels like it has a loss of power and then resumes. It feels as if a huge gust of wind hits me. In the past I have had the CEL come on and then go away after a full tank of gas has been used. This has happened at least 3 times in a year or two. The only recent thing done to the vehicle has been charging the Air Conditioner. I thought the compressor was the culprit, but this problem happens with or without A/C running. I have done the following to rectify the current problem with zero success.

  • Changed the Spark Plugs (Not the cheapest ones, but not NGK's) Gapped at .044 per Autozone tech and manual
  • Used premium STP Fuel Injector Cleaner in the gas tank with a full tank of gas.
  • Changed Air Filter.
  • Oil and Filter changed.
  • Purchased throttle body cleaner and sprayed the outside of the throttle body (Thinking the cable might be seized up)


I am grateful for any suggestions and appreciate you taking the time to lend your expertise.

Do you mean the problem has occurred this much or the CEL coming on?

When the CEL came on did you have the computer scanned to see what trouble code(s) it was storing? If so, what were the code numbers?

The CEL has come and gone several times. I attributed it to bad gas. The current problem has presented itself only recently and is still here. I did not have a code reader hooked up to the vehicle when the CEL light came on because it went away after a full tank of gas had been used. I will take it to Autozone today and see if any codes come up.

The more information you can get, the better chance you may have formulating a strategy to figuring out where to look for the culprit.

Even though the light may have gone out. The engine controller can store the code(s) in history.

That assumption couldn't be any less likely.

The "check engine" light is an indicator for a system that monitors many electronic functions in the system, also called the "malfunction indicator lamp" (MIL). It can come on for any of hundreds of different causes from any of the systems that the computer monitors. Some are very important and can lead to further component or engine damage and some are emissions related not as serious but still a problem and need to be repaired.

Your first step is to have the computer scanned to retrieve the trouble codes that were set when the check engine light came on. Those codes will give you specific information about what the computer saw and will get you pointed in the right direction to find your problem. With a 1996 or newer and some 95 cars and you have an AutoZone or Advanced auto parts in your area, they will read them for free. Once you have these code numbers, we can be a lot more specific about what your problem may be.

Yes, that helps a lot. The computer is seeing an issue with the Crank Sensor signal. It could be a bad sensor, a problem with any of the related wiring or even the computer itself.

I Just replaced the Crankshaft Position Sensor and the problem is resolved. BTW, it was a Pain in the A$$. It resides behind the timing chain cover. Had to pull the passenger wheel, plastic shrouds, tensionor pully, static pully, harmonic balancer, and then finally the lower timing chain/belt cover.

Tools used:

10 through 16mm wrenches and sockets
Cheater Bar with 1/4 end (Used to put the Serpantine belt back on the tensionor)
Flat Tip Screw driver (Used to pop off the plastic plugs that holds the shrouds in place)
Small plyers
Jack
Lug Wrench
Jack Stand


Thanks to all who provided advice.

LOL......... there are some a lot worse that that one.
Glad you got it resolved.

I will close this thread now to prevent spamming.
