This is on a 97 with the 2.2L engine. What would cause the #4 cylinder to fill with raw fuel. Other cylinders are ok.
This is at a shop but my pockets aren't deep enough to keep the mechanic guessing. They changed the fuel regulator figuring that was the problem. Then found it was only the #4 cylinder so they tried an injector. Still no improvement. Then he was going to change out the fuel rail (with a used one), but then found that in 97 the rail is integrated with the intake manifold.
That's where i told him to hold off.
I'm several hours away from the car so cannot look myself. This is info from my kid and the mechanic.
If you have any great ideas, I'd love to hear them.......thanks
 
Are you sure the spark plug in #4 is firing?
