I have a 97 explorer 2 wheel drive milage 160000. When I get to about 30 or 40 and try to speed up it shakes like the engine is clogged and about to fall out. Had the tranny replaced, plug wires, belt and air filter. Any advice would be great.

The tires are in pretty good shape. There was a test on it that said system running 2 lean. But when I get on it I can blow through it and it stops. I have no idea where to start.

Okay. Lean would mean not enough fuel. I need to the trouble code to get you started. Or, if you have a fuel pressure gauge with a long enough line to allow you to tape the gauge to the windsheild, you could drive it and watch the pressure at 30-40 mph, or when it screws up.

It's difficult to speculate without any PID data. Are you going to try the fuel pressure test?

If the fuel pressure was below spec, we would verify that the pump is getting power to it, and that would indicate a fuel pump problem. The key to making this work for you, is to try to prevent throwing parts at it and hoping for a fix.

There is a flow of diagnosis that has to be used in approaching problem solving. That is why the trouble code is so important.

Do you have or have access to a basic code reader?

But if the engine light is not on will it read a code. I will get a code reader if I have to. Also thanks for the quick responses.

Didn't you say it had a lean code? That's a code :)

Fuel pump failures and loss of power to fuel pumps hardly ever set codes. Thats where sperience comes in. Been dar, did dat.

Did you give me any feedback? Good or bad give feedback.
