EGR valve, low flow by thundercat
Feb 13, 2008 (4:05 pm)

I have a 1995 cougar, v8 4.6L. I have replaced the EGR valve twice and the other 2 components that work in tandum with it and I still get the egr error code pop up. I have made sure the exhaust tube is clear of build-up and it makes no difference. Is there a control module that is responsible for the operation of the egr and it's components? Anybody have a fix??

Since it turns over when you bypass the solenoid, either the new solenoid is bad or there's something with the wiring to or from the solenoid.
 
You might want to post in the general "No Start" Problems discussion over on the Maintenance & Repair board as well

Hello all, sn5bah here, maybe one of you can help me with this one. My 2000 Mercury Cougar gauge shows that it is overheating, the thermostat has been removed and the whole system flushed. New water pump installed. Water pump belt broke off yesterday. Is this hard to replace, payed a mechanic to replace the water pump, but this time I want to do it myself. Need a quick response, this is my only vehicle.

V6?Could be IMRC control unit faulty.This device controls the opening of the valves at approx. 4000rpm to allow max power!

tcastillo
did you ever get a proper diagnosis for your problem?
Was it in fact the IMRC???

Crazy Gauges? Help an old CSG member out by advocatus

Hello CSG,
 
Long time no chat. So it seems recently my gauges started going the full distance from 0 to 160 upon startup. Is this new? Has the cougar always done that? I don't think it has. All of my gauges go the full distance. Does your cougar do this? Is it possible that it has always done this, and I haven't noticed in 7 years?
 
That and tonight the cougar didn't start. It just clicks. I'm thinking the battery is low, though the highlights are bright and the internal stereo, lights and etc are fine. I've been warned a couple of times that the battery is low. I think that will be the first thing I change.
 
What do you guys think about my gauges.. am I just stupid?
Thanks!

2000 Mercury Cougar Problems by lmoreno3

Need help with my cougar. Temp guage shows hot. I have replaced the coolant temp sensor three times Bought two new ones and tried one from a junk yard. One of the new ones did not mark at all on the gauge. The one from the junk yard and the other new one mark hot. I have installed a new water pump, replaced all of the belts, replaced the radiator. Put a new radiator cap, had the whole system pressure tested. All checks out to be good. Pressure holds up, no leaks anywhere. What can I check to fix this problem? Any and all help will be greatly appreciated.
