Re: runs rough all speeds
First thing i would do is place a vacuumn gauge gauge on the mtr 17 to 21 inches of vacuumn is good and a steady needle. i execpt to see your reading a little lower than that because of the miles, and if the needle is not steady you may have some valve train wear.have you checked the timing now would be a good time, with a vacuumn gauge . when it runs rough dose it do it more after coming of the hwy after you have been running at hwy speeds let me know kdc744

I have a 1999 Ford e150 van and the van runs good on the highway and rough on the city street. tries to stall at red lights and stop signs. I took it to a garage and the computer says it is running lean on both banks.
EGR sensor, just replaced it an hour ago and started to remove the egr valve. I can't figure out how to get out the bottom bolt. and is there anything else holding the egr valve?
The garage said to use carb cleaner and spray it out. they told me to ry this before you buy a new one. It's 11:30 pm and I wish i would have just got a new one. I don't want to go through this again.
Help me get this off and if possible direct me to some photos,
Running rough and misfiring is usually a one or more bad spark plug wires. Don't go back to that dealer. Replace the wires or have your mechanic do it for you. If you replace them, take one off at a time and install the new one. If you put the wires back on in the wrong order, it will misfire.
