check the grounds.98...so it doesn't have an egr valve. my guess is i have a short somewhere, my alternator is shot (though it reads 14v on the gauge when the engine is running) or the crap battery is really crap (8 months old) my xj is cranky, when it doesn't get enough voltage it always resets the idle. after it runs for about 10-15 minutes, its all good again. it always is fine in the afternoon, but its been getting down pretty cold at night since thursday
Seriously, 9/10 out of ten when a friend says they need a new battery I clean all the cables and grounds and it runs fine.
My piece of junk 91 has been doing this to me. So I have been parking it on hills. I can pop start it in 3 feet now.
I think my duralast battery finally died because I only drive it every few weeks and it's getting cold.
I lol'd because I know how that works.
I live on a hil, my driveway is sloped. I could manage to coast it backwards with enough speed to make the 90* turn and then coast down the hill to roll start it.
