Running very rich.

[QWK GN]

I had my 86GN out for a little drive tonight.The car was running perfect, then it started to run rough and I could smell gas from the exhaust.I pulled over and checked under the hood and everything seemed tight and connected.It was dark and raining out so I might have missed something.The car only has a few mods( hot wired xp pump, adj fuel reg,blue tops ,Red's 93 chip for blue tops, smc alky kit,heated o2) I left the car at a friends house and will check it out tomarrow. There was raw fuel in the exhaust pipe.I think my heated O2 went bad,it is about 5 years old. I don't run leaded gas. Any suggestions as to what happened or what to check out?
Thanks,John O 86GN

Any SES light? The 02 sensor probably died on you.

I don't have any scan tool numbers.I am going to hook one up tomarrow.There were no codes.As soon as the car started to act up I parked it.It was starting to rain,so There was'nt much I could do with it tonight
Thanks-John O

check i/c hoses..

I checked all the vac lines and I/C hoses,they were all good.Checked adj fuel reg -ok .Replaced O2 with a new stock one .Started car and drove around the block,still ran bad and smelled of gas but no codes..I replaced the mass sensor with a new GM one I was saving,no change.I hooked up a scanmaster and the #'s for the O2 were ok for the way I was driving.The coil pack ohm out ok, but I am going to retest with Casper's coilpack tester tomarrow.I think an injector is stuck open.I got the injectors used and think they have more miles on them than I was told.I'll pinch off the return fuel line and see if fuel pressure bleeds off.I'll also try a different chip for the heck of it.Is there anything else I should check?
Thanks-John O
