This is one of the most common no start or random stalling problems with these L-jet ECU's. This is a VERY hard to find ECU as most of these cars were gone long ago, making finding a good used one hard and a new one even harder. If yours does not have this problem, keep an extra ECU in the trunk, you might some day be glad you did... These units now have to be special ordered from most dealers new for big $$ (often times over $1000!), and finding a good one second hand is getting to be a very hard chore. We offer a 30 day warranty on this.
