Ran Codes, Any help would be appreciated.

[KC96LSC]

Car sat for about 4 months, had a bad A/C compressor. Got it fixed and had Check Engine light flash about 15 time then stopped. It went back to a solid CE light, my CE light is on all the time because of hollowed out CATS. I've been driving with out the 2 CATS for a number of years. Here are the codes that came up:

Any advice would be appreciated.

You mean IMRC pass side.

P 1537 You mean IMRC pass side. PO412 there is a solenoid that controls when vacuum goes to the air inj valve on front of engine?

Sounds like one of the issues to me they stick and throw a code. Or its not functioning at all which would be no surprise on a 96.

Yes, that's what I meant to say. Hope fully he can get them operating with a good Seafoam treatment, and doesn't have a torn diaphragm in the IMRC actuators. I think someone either here or LOD did a replacement thread, even taking the can apart and replacing the diaphragm. Otherwise the scavenging hunt continues for these precious little beauties. If you get replacements or restore your IMRC's back to operation, take the time to block off the EGR and get some one to remove that function on your chip.

Just wondering, the intake manifold has a leak on the Right side (Pass) very 1st port. It's literally been that way for years. would that all of a sudden cause it to start giving the IMRC code. The car has ran a bit rough at low idle but never enough to make the engine not run. I'm sure my gas millage isn't as good as it could be. I'm listening to the car run right now and it sounds like it has for the last couple years. If I drive it could it break the IMRC loose? The car has sat for the last 3 to 4 months. Can driving it hurt the car? Thanks guys.

Also, what other IMRC actuators will work? Does the Cobra 96 to 98 or even just the 96 Cobra, and I also saw people saying 97 & 98 Mark VIII will work, I'm not buying that, but I have to ask?

The only IMRC that will work is the 1996 Mark VIII specific model IMRC. They are unique. That's why they're expensive and hard to find.

If its sticking it will throw a code then free up, then stick again and throw a code repeating the cycle.
If the actuator is bad.... leaking vacuum it is broke and a 96 only part Sap took one apart and repaired a tear once so they can be rescued.

No
Just no fun

Ford Nut, thanks for answering all my questions.

if the IMRC actuator is in fact bad,

install 93-95 actuators, they function the same, and i have been told you can tune out the CEL for them.

I wish I knew better about the 96 having unique IRMCs back when I first got my car because there was a 96 at the yard. I pulled the IRMCs out of a 93 at the yard recently, just to see how hard it was (wasn't too bad). I would have bought the 96's IRMCs for resale for sure.

I read that too, not sure what gets changed in the tune, also recall reading you need to run a window switch to control them.
I wouldn't know.
Did find this thread.

No problem

Go Royals!!! :Beer

Royals are destined to win the World Series this year. It's been a long drought for us. To bad we're not going to get to beat the Cardinals again.
