yep sounds like your burning off some gasket stuff. have a look and make sure theres no wires against the exhaust

 

Lol I got a bit excited and panicked when saw the smoke. All is well now its still missing but not
nearly as bad as it was before the 02 change. I get a slight stumble at low rpms usually when i take
off after a red light and while cruising but at high rpms it runs like a champ. Ill have to just keep probing at it for the time being
I appreciate the patience with the lengthy thread

 

So i finally was able to hook up my 95 scanner, i didnt get any DTC codes but i have some codes showing up under electrical faults tab. My Fan 1 low and Fan 2 high relay are open. EGR solenoid open ,TCC (transmission) solenoid is open, VAP purge CCP is open and VSS open. I am assuming one of those is causing the misfire and stumbling. I will pull the EGR off this weekend and see if its creating suction but other than that im pretty lost.

 

look at the evap system too.

 

ok so screw me. I was attempting to replace the evap solenoid and somehow ended up having to remove my intake, heres how that happened lol. The evap is so far under the fuel rail i couldnt get a socket on the bolt to remove it so i took the fuel rail off and noticed 5 out of 8 injector pintel caps fell off into the chamber again. Good thing i removed the rail and caught this. No wonder that nasty stumble popped back up again. So to wrap this up my question is can i put some kind of heat resistent super glue on the top of the cap to keep it on the injectors? I pushed them on hard and heard the click so i thought they wouldve stayed in place. I figure they have some kind of function so id rather not have them off the injectors.

 

what caps? picture? photobucket works good.

 

The caps on the end of the injector near the spray needle.

i have never seen those before. is this a stock intake

 

yea stock intake, i just upgraded the stock injectors to some densos a while back. nothing too crazy

 

can you use o rings with the injectors and get rid of those things.
