Most likely your engine is getting too much air which causes the ecu to dump more fuel in order to keep the AFR in check.
Have you driven it, does it have good power? Does it also surge under load or just at idle? Have you tried spraying around all the usual places to be sure of no vacuum leaks? If you close off the intake for just a second or so does it die quickly or keep running? (some cars you shouldn't cover the intake or you may pull the plenum O-rings out of their seats and if you already have a leak this could potentially make it worse just FYI) |
