Some DA didn't put a K&N or other oiled air filter on it?
Heading home now to check batt and charging sys, I'll take a look. Temp gauge seems to be working normally.MAF dirty or bad conex.
Disconnect coolant temp sensor and report
...also look for interior grounds.
the real question was... If I get a PCM fro...
JDThank you all for the advice and insight. The starter seems to be working fine, sound and effect. I did find and clean 2 ground wires in the engine bay, one large braded by the battery box and another much smaller one from the engine to body on the passenger side. No sign of chewed wires yet, the engine compartment is unmolested, but it's cold out there. The car sat for 10 months IIRC, before that no mice as far as I know. She was very musty when I got her, I plugged a dehumidifier in a few times to help dry her out. Worst was the first time, it drew a quart in about five hours. Never more than a cup since then. What's under the dash may be a whole different story as far as nibbling mice but so far nothing. I will rip it all apart this weekend and find out for sure.
It's got Calif emissions, the real question was... If I get a PCM from a car with Calif emissions, do I need to have it flashed or should it be plug and play?
Next step is going into the cabin. loose connectors grounds and get the number from the pcm. Mabey crack it open and look at the board for melted terminals or shorts. Gotta tell you... I love modern technology. And I thought rewiring the bike was fun. Yay!
Thanks AUTOMAN. Idea being the car will run on factory presets only and the pcm will not communicate?JD
disconnct your ECT (engine coolant temp sensor)
This will force open loop.
we go from there
pcm still works, just the o2 f/a feedback is disabledThanks AUTOMAN. Idea being the car will run on factory presets only and the pcm will not communicate?
At that point what misbehaves is a possible culprit???
send it over when u get the infoI can pull the ECT at next brake and idle it a bit, won't be able to drive till this afternoon.
My scanner will give me live data, fuel trim etc but I don't know the acceptable parameters.
That may be listed in my shop manual but I doubt it.
Thanks Jim.Have you tried Rock auto? I buy expensive stuff like computers from them. Can't swear to it, but in the back of my mind I'm thinking they'll sell you the right one based on your vehicle. Maybe they ask for part of the VIN?... dunno, but I'd try something like that or ask at your parts store. There's gotta be some way for 'em to know if a cali box is plug and play or needs flashing.
Fwiw, I'm guessin' it's plug and play.
Good. Default ECT is 194F. NOTI pulled in the driveway ang got this off live data.

So I pulled the ECT. No start WTF?
Plug it back in, no start WTF???
Ok dummy what'd you do?
Oh hey what about that big grey plug you unhooked to get to the ECT
Unhooked the ETC and reconnected the other vroom. YAY!
Took it around the block it holds idle but does get close to 400RPM which is stall rate but pops back to 700/800RPM.
At least I don't have to two foot drive.
Still stumbles at all rpms, much more at lower rpm like when gently cruising/coasting with foot just barely on the gas (buck stumble buck)
Reading 2 codes P0170 AND P0102 mass air and fuel trim respectively
Wants a little throttle to start or will start and die.
Both fans run consistently, I unplugged them.
It's below 50° for highs and when I go to work it's in the 20s one stop light into town one on the way out.
I'll run the heat on high to cool the engine figuring less draw than the 2 fans.
The wife got the day off so I took her car today. Just want to avoid tickets and especially court surcharges.
No reports till tomorrow but I'll find out how she runs cold to hot and get any codes.
