    89 Conquest misfires on cold start & poor idle when warm

    I have a strange run of issues on one of my conquests that I can't seem to figure out. To start off, all emissions are deleted and I have a catless downpipe. The car has an OVCP with a turbo XS blow off valve in which I've confirmed doesn't leak by removing it and putting in a block off. The car also has a freshly cleaned & sealed tank, new fuel filter, new fuel pump, new fuel lines, Southbay injectors, SPA adjustable FPR (set at 48 PSI), freshly rebuilt throttle body, and new injector clips

    So when will we see that Yellow CQ….

    pop up on BringATrailer?   I guess the FS post was deleted of the guy posting his 1-owner Yellow 89 with 30k miles.   And wanting to sell it with no price like SQC is an auction platform. He wouldn’t throw out a price as he thought it would hurt his ability on BAT if people knew his reserve price.  People will pay what they’re gonna pay regardless.     Anyways, I was truly interested in it but I guess we are waiting to see it show up on BAT.

    So I was at a performance shop yesterday, checking my startup voltage on my 87 conquest, which has been modified quite a bit ,the batteries in the back, and the owner of the Performance shop told me to go ahead and turn it over. Well it did start, but it was kind of hard to start. That’s another subject. But it was smoking, a fair amount. Not pouring smoke, but definitely noticeable. So, haven’t really seen that before with this car, except the last time that the motor was hurt a little bit. So

    Hard start after warmed up

    I have an 87 conquest. I am running a Holly EFI standalone computer ,car fires up fine with cold start and will fire up fine if it’s been sitting for at least an hour or more after reaching full operating temperature. But, if I shut it off after it’s fully warmed up and then try to start at five minutes later or 15 minutes later, it won’t start or as hard to start. I know a lot of the community  runs aftermarket computers and may have some thoughts on this. I will tell you that my fuel pressure
