Hi, I hope someone has an idea on this. 88 conquest. When I take off my wideband reads 17 and the car will stall if you don't fanese it until you get under way. Once you get going it runs around 12 to 14. Under boost it runs at around 11-12. We did check the TPS and it appears to be good. I believe it has a Gen 2 with a K&N air filter. It does have a walbro fuel pump and runs fine once you get going. The problem is only when starting out. Hot or cold it doesn't matter. I am looking for some possible causes. Thanks for any help.
