The problem continues
http://www.automotiveforums.com/vbul...ht=cough+grind
It's been at a mechanics shop for a week. He has run through every computer, electronic, mechanical test he can think of. He has even taken the engine physically apart, and cannot locate the problem. He says it sounds like the throttle position sensor. What do y'all think? Thanks! EDIT: Compression now checks out at: #1 - 186 psi #2 - 184 psi #3 - 185 psi #4 - 186 psi Is this too high? EDIT (again): Those compression values are when the engine is turned over 7 times. When the engine is turned over 12 times, they range from 189-194 psi, and when turned over 18 times, 195-199 psi. A thought just popped in my head, could a clogged cat be causing this entire problem??? Thanks!

Re: The problem continues
Mechanic gave up...says I should take it to a dealer. I've been thinkin on this "clogged cat" thing overnight...I've got an enemy in the neighborhood, don't who, but I know hes there, cuz he's egged my mailbox 4 times, my car once, my girls car once, and my girls' mom's car once...could he have stuck an egg up the exhaust pipe and when it popped it caused it to plug and cause back-pressure? I pick the car up today after work (un-fixed).

Re: The problem continues
The compression sounds fine, but both the crank and the cam timing marks should be dead on (when you turn the motor in the right direction, turning it by hand back-ward will show the slack.
Does it run poor both hot and cold? That one funny colored cylender may have a bad injector. I think the EGR valve is worth a second look. It is kinda common for the 98+ fuel pumps to go bad, but I'm not so sure thats your problem. It's kinda strange your one plug was smashed closed, you could of dropped a valve seat.

Re: The problem continues
The timing marks are dead-on since I replaced the timing belt (before it went to the mechanic). That (replacing the belt) did make a difference, but didn't fix the problem.
Can apply 8 hg of vacuum to the EGR valve and the engine tries to die, and on the other side, putting in a blocking seal between the valve and the manifold makes no difference...so according to Haynes, the valve itself is fine. It runs poor when both hot and cold, however, it is a b*tch to start when cold. I've checked the injectors and so did the mechanic: #1 - 18 ohms #2 - 17 ohms #3 - 18 ohms #4 - 17 ohms Everything I've checked said that should be fine. I've also pulled them out and visually inspected them and replaced the o-rings. I have no way of checking fuel pressure, but the mechanic said pressure is fine, both running and not. How would I check if I dropped a valve seat? Would that cylinder not lose compression? Thanks for your help guys. I'll link this thread in escortracing.com.

Holy crap man. A lot of work and worry for plug wires.

Re: The problem continues
lol...yup, BUT, I don't regret one thing I've done to that car, cause it was all beneficial and would have needed to be done anyways. Now I'm gonna go home and fabricate a ram air system. hehehe

Re: The problem continues
lol...I actually had the wires in my hand, near the beginning, but I decided to "test" them instead. Couldn't see/feel any arcing. Replaced with wires off another car, and a couple other things I'd heard from friends and mechanics, and everything pointed towards "good"...kinda funny. If I'd bought those wires with the air filter and plugs, I'd been fine.

Whew!!! But thanks for the info! Did you do an ohmeter test of the old wires and new?

I tested by looking at them at night, with the car running, in a dark garage, to check for arcing. Another test was also (really risky, but I was desperate) hold the wire, and move your hand down the length of the wire from the coil to the plug while it's running, if you get a 50,000 volt jolt, replace 'em. How do you test 'em with an ohm meter?
