and has a solution.
1990 LS400 all stock.
A while back when I started it, it ran great for 5 to 10 minutes, then it just died, started right back up and would run good only holding the throttle and maintaining over 1800 rpms or so. Let is cool down and did the same thing for many other trys. So put it on back burner to work on other projects.
Got a bit of time and had extra used parts so I replaced the airmeter, and idle control valve, it started right up after sitting for a fairly long time, and ran at about 1600 rpms and slowly kept climbing to about 2000 and leveled off there. If I slightly stomped the gas pedal the rpms would fall off to 600 or so then right back up. So you think I have a bad airmeter or idle control valve? Have others experienced this with bad ecu's? Thanks.
Oh and when the problem originally started it had an airmeter code, 27?? I for get. No codes now.
