Message	It's not surprising that a faulty CTS causes such problems. It's effectively changing the mixture A LOT. Faking out the ECU with spurious temperature values (differing resistances) is a very effective troubleshooting tool for fuel problems. I checked mine with ConZult and if I remember correctly indicated ~170F. Connector looks clean --sprayed with electrical cleaner. Gotta git me one dem new fangled ray guns you takin about ;) Zarcasm(Hfd, CT) view My Profile (click here) view My Technical posts (click here)
