2002 Ford Focus idles rough
Hi, I'm new to this forum and am in desperate need of some help.
The Serve Engine light came on and I took my 2002 Ford Focus to the Garage. The Computer identified the problem as a faulty EGR Valve. The mechanic called and told me that he also suspects some crossfire on the plug wires and advised to also install new wires and Plugs.
After installing the wires and plugs, he had some problem in taking off the EGR Valve, said it was rusted in. He had to take off the Manifold because the bolts sheared off, and that I had to get a new exhaust manifold.
It is now 4 days later, he has everything installed, but now the engine idles very rough, the computer shows no error code and he is trying everything to find out what could cause this.
I would appreciate any suggestions as to what could be the problem
Thanks for any replies
