Low idle stall 90 XJ
My 90 XJ 148K has a low idle stall problem. I replaced the EGR valve
yesterday and drove it for about an hour with lots of stops without a stall. It died on my girlfriend at 2 stops this morning (it was warmed up). It runs good other than the stall problem. Fuel pump, filter, CPS, O2 sensor, TPS are all less than a year old. Any ideas? |
Re: Low idle stall 90 XJ
The first step with idle level problems is to clean the throttle body and
idle control valve. With that kind of mileage, it could be gummed up. Just in case you don't know this, you should be replacing spark plugs and other ignition components from time to time too.

Re: Low idle stall 90 XJ
I would be cleaning the plugs and sockets on the throttle body with a
spray contact cleaner. WD40 will work in a pinch, but the electronic stuff is best. Lots of times that is all the problem. Changing things like the TPS only cleans 'half' the trouble areas. Out TPS went 'bad' 5 or 6 years ago and the clean has kept it working.

Re: Low idle stall 90 XJ
It may be your idle step motor, bad connection, jammed with soot,
or not working and needs replacement. Looks like: http://members.cox.net/wilsond/tb/tb.html That's it's job keeping the engine running fast enough not to stall.
