In general, yes. OIL fouling of the spark would be the correct assumption. However in this particular motor, which is notorius for blown head gaskets and lower intake manifold gasket leaks, allowing coolant into the combustion chamber I would take a look at these first, and in order. 1. fuel pressure, this all started after you ran out of gas correct? ...

I have a 97 suburban. I am not sure how similar things are. I have replaced lines/hoses/calipers/wheel cylinders on this truck and spent hours of time and over a gallon of fluid trying to get it bled correctly. A couple things that I've learned and have helped. If the master ran dry, be sure to bench bleed the master and ABS. Remove the lines, install ...

If you've changed the calipers and the pedal now goes all the way to the floor, chances are that you've introduced air into the system whilst you had the calipers off. To fix this, you need to "bleed" the braking system. At each brake caliper / wheel cylinder there is a bleed nipple or bleed screw. The basic procedure is to start at the wheel furthest ...

P0171: oxygen sensor in bank 1 has detected a lean condition (too much oxygen in the exhaust). the side of the engine that has P0171 is one of the more common trouble codes. This code is triggered by the first downstream (front) O2 sensor. Bank #1 refers to the side which has cylinder #1, In a 4 cylinder it is the cylinder in the front of the engine. The ...

Check the tension on the serpentine belts at the front of the engine - sounds like they're a tad loose. It may be something else, but start there.

From my research on surging idle..A possible solution-TPS(Throttle Position Sensor) connector. I read on a diagnostic webpage that this guy disconnected and then reconnected it and the problem was solved for 3 weeks. In theory it makes sense when the ECM loses the input from the TPS sensor it falls back on a default setting until the TPS is reacquired. Maybe ...
