I just got a hold of an 87 yj 4.2L with no mods that I'm looking to get running smoothly again. I have the typical engine kill when I stop that I'm working on that I've found so many other people with the same problem. Looking for some help with that as well as a couple other this.
I've found info on the engine die-out, but my main issue is a bad pulse air system. Both air control valves are bad and the one I was fortunate to get hold of to replace went bad because I didn't realize the check valves were bad too. So it screwed those up. Can I remove the whole system and still be emission legal in california? Are there mods to replace it (new exhaust system?) and keep it legal, or is finding replacement parts the only way to save my chance of passing a smog test.
Please help me out. . . I'll be checking this daily for you help[addsig]
