Default another day, another code...

Swapped ECM's on the zr-1 today and took it for a drive. the car is no long banging when it misses but it's currently running out of vacuum in 5th and setting code 61, which is different then the DIS code it set last time which number I can't remember. I had Marc Haiback check the system at carlise and the pump and actuators checked out fine. However today I get this code...this is getting old, not sure how much more of chasing codes I can take.

Kevin, sorry to hear of another code to chase. Hope it gets rectified soon.

Have you changed out injectors (new SS ones)/ coil packs / spark plugs / wires and fuel pumps?

It's hard to chace down codes unless all the preventive maintenance is done. I can't remember what you said was done...

What's been done to the car in the past 5 years? Anything recently?

New FIC's, coil packs, pumps and filter aren't new but I don't think that's the issue, not getting a fuel code or anything like that, plugs and wires are new as of last year. Talked with Marc and he thought it was a bent pin in the DIS making bad contact when I had the old ECM in the car and had a DIS fault code. Spoke with another friend who thought it was the ecm degrading via heat soak so I swapped that today and ran the car. 1-3 pull hard, 5th ~2500 sets a code 61 but it's no long banging when it stumbles and will still pull but just set a code. Idle is fine, driving around is fine, secondaries in 1-3 are fine, didn't try in 4th, that's way to much "spend time in jail no license insurance will love you forever" speed for me to do on the street.

Marc looked at the car at carlise, the system holds vacuum fine, the secondaries open fine.

Past 5 years... well there was:
02 sensors last year
fuel injectors last year
plugs last year
wires last year
complete ac system replacement this year

and that's what I can remember off the top of my head, I'd have to look at my records to see what else was done but if it was something it wasn't major. Car is stock except for the front calipers/lines, the haibeck chip, and the coplan air duct. I wouldn't mind these issues if the cat had been through 4 shops and multiple engine builds, that's to be expected, but this is a factory car. Sure it's 23 years old but my this is getting excessive. I'm about ready to list it for sale.

Kevin:

Electrical gremlins are extremely difficult to track down and eradicate, especially ones that are intermittent.
Took me better part of 3 years and untold hundreds of $$$ to finally track down to bad fuel injector to ECM contacts because I had stupidly shoved in my Digital Volt Meter's probe to check them when my injectors took a crap.
Sounds to me like you have a similar, although different gremlin.
Start backtracking to all the connecters that you have futzed with over the years.
Betcha you'll find something.

Sometimes it's the simplest things..........

Feeling your pain,


'Crabs

in talking with my wife I can't see the forest for the trees right now, I'm going to call a friend this week and talk with him and see if he can help me get a better perspective on it. I'd really like to drive a near stock car with it before I did tune them out but I don't think that's going to happen
