Hi, I have a 98 Ford Escort with 189900 miles. When I drive my car, I can feel vibration in the gas pedal and the steering wheel. It vibrates more when I'm idle than when I'm driving. The Engine also sounds a little louder when I accelerate but not when I'm cruising. My check engine is also on and it is because of an egr air intake insufficent. I'm not sure if I should get a tune-up(as it hasn't been done in awhile, or if it has something to do with the egr.) Thank you.
Do you
have the same problem?

Pull the egr off, clean the port under it all the way to the throttle plate, I use a length of steel coathanger. Put it all back together, reset the codes, if light comes on again, replace the EGR position sensor, thats the one the two small hoses from the exhaust plug into!
This is for a code P0401 EGR insufficient flow?

Check the motor mounts too. Does it make a clunk noise when you first hit the gas?

I was just commenting on the vibration, sounds like it needs motor mounts if you can feel it in the wheel and gas pedal

Hi, Thanks for the help. I thought I might have to do something with the motor mounts. By the way, how much does it ususally cost to fix and/or replace the motor mounts(estimate).

Really depends on which ones need replacing and where you buy them. Anywhere from 3-4 hundred

Just want to insert my two cents. Everything posted is perfectly on track. The vibration is coming from a plethera of Ford research and development failures. The motor mounts are only part of the service procedure outlined by a Ford service bulliten. The rest of it has to do with replacing some of the engine cradle mounts. When the get old, they stiffen up and don't absorb engine shock. If you contact your local dealer you may be able to let them know that you are aware of a service procedure to correct this mistake and ask them for a copy of the procedure. If you have a good dealership that works with it's customers, they may be willing to divulge the info. If not, I may still have a copy in storage, but that's not for sure.

What would be the cause of the loud clunk when first hitting the gas with the Ford Escort ZX2? That is something I am currently dealing with, and it is on/off, not very consistent. Thanks!
