Re: Corsica misfiring after rain (nowadays problem with IAC valve)

My idle is quite fine, though its sometimes quite low, around 600rpm. Only real problem is starting, where IAC seem to have effect on, since with the old, broken one the car started just fine (in most situations). I actually took picture of the iacs four wires, but is there somewhere pinout so I cou...

Re: What (scan) tools do you use?

Hmm, since this thread seem to be suitable for my little question I guess im going with this.

My Corsica is -93, with ALDL. Does that mean its obd1? What kind of data I cant get out of that box (except jumping codes with a+ b pins of course), and specially, with what tool?

Re: Corsica misfiring after rain (nowadays problem with IAC valve)

Moving to next suspect: IAC valve operation. Seems like also my current IAC (stolen from another Corsica) is also stuck. Cant move the pintle with my fingers? If i remember it right, I could move my previous IAC pintle easily with fingers when I cleaned it up. I also managed to find out from interne...

Re: Corsica misfiring after rain (nowadays problem with IAC valve)

Ok, Injectors tested. No leaks. Put power on while all injectors were connected. When you put power on with key, each injector sprays one load of gas. I think this is supposed to happen? Made two leak tests: First on, i disconnected each injector wires, and put full pressure on the line. None of the...

Re: Corsica misfiring after rain

Nah, dont worry about it. Of course I put jars under injectors. Its also -5 to -10 here in Finland so nothing burns nearby. Gotta take look for the relay... I actually am coming to conclusion that its still something with iac valve. The engine started quite fine with broken iac (stuck), after i put ...

Re: Corsica misfiring after rain

Hmm, ok. I'll check it out and give really short pulses. Its safe to run start motor while injectors are pulled out?

Also, where is fuel pump relay and how to bypass it? To get pump run constantly?

Do you guys think lamda would be the culprit for hard start while hot?

Re: Corsica misfiring after rain

Hm. I already thought im gonna give max 1 second pulses to them with wires, to prevent overheat or sth.

Maybe I'll hook up 9v battery also.

Re: Corsica misfiring after rain

Yeah, lets see. I think I am also gonna fire up each injector straightly from battery to see how they spread fuel and do they leak after spray has ended...

Re: Corsica misfiring after rain

Yeah took the upper intake apart today. No big deal, took like 2 hours while doing it carefully (first time for me with this engine). Didnt have to touch alternator. Took out EGR, tbi body and cable bracket, map and air intake box of course. Already removed four bolts holding the rail, and also remo...

Re: Corsica misfiring after rain

Starting to suspect my injectors. There is always pressure (=starts well, havent measured pressure) on cold start, which basically rules out fpr. I think im gonna take upper intake apart soon. To test if injectors leak, can i just raise fuel line with injectors from engine and put power on to check ...

Re: Ignition switch/starter not engaging/intermittent charging

This junction is at least in 3.1 -93 Corsica near ICM module, below the front exhaust manifold. Take look between engine and battery, near air intake box.

Dont know if beretta has different wiring, but I suppose you got same engine and year model so...

Re: Corsica misfiring after rain

I agree it's too cold to be working on cars in this weather. Need a heated garage. I'm interested to know how the leak is. I know a water leak in this weather causes the floor to become blocks of ice in these cars. It's getting just as bad around here, well for Beretta's that is. Lucky to see just ...

Re: Corsica misfiring after rain

The crank sensor was just a thought. Oh man the torque that they have is nice, sure miss that low end power now that I have the 3100. Did you locate the test lead?
