'00 Intrigue - low idle/dies cold, also P0442
I've been having annoyances with my Intrigue for almost a year now. It started last year. I used to be able to just hit the key and drive.
Last October it started not running at idle when warm. I found the throttle body was gummed up and cleaned it out. After that, it wouldn't idle when cold. When it dies cold, it starts immediately when I hit the key, provided I have the throttle cracked open enough to keep the R'* up on my own.
It idled warm just fine...until the idle got erratic. Even when warm now, the idle will sometimes be erratic, bouncing between about 400-450 up to around 600-650 and may sometimes (rarely) die (when warm). Other times, most times, it will idle around 700-750 steady, faster if the engine is hot.
A little repair history:
First, last November, I failed emissions with a rotten secondary pump injection motor (replaced off an '02 Cadillac).
In December I replaced tie rods, front bearing, and the sway bar.
In the last 6 months it threw a code for the TPS (replaced) and the IAT (replaced), then CPS went out (replaced, of course).
I got a P0442 two months ago - I replaced the gas cap, which cured it for about two days, then it came back. I just replaced the canister purge valve this past Sunday. The light came back on Tuesday, P0442 again.
Another problem, possibly related or probably not, is balky power steering. When my ex had the car the P/* system was leaking and I had to put fluid in it several times. Now it'* not leaking (I did nothing to the system), but the engine has to be turning at 1000 or better to get any power assist on it. Pump? Rack? Electromagnetic assist? Related to the above?
I'm mystified as to what'* related and what'* not. Failing anything else, I'm planning on replacing the filler neck and/or the vent solenoid, but I would like to nail it down and do the job once instead of guessing. I need to get this thing through emissions to get it licensed. I'm almost a month out of compliance.
I'm planning on buying an OBD-II connector for the computer and installing OBDWiz on the laptop.
Sorry to be long-winded, but I want all the data there for discussion.
