glad to see you've put your nice avatar back :bigok:

yeah i missed this one

thanks

im going to check that out today

Did you put in 550cc T2 secondaries? I am having the same problem with my car. Tested the TPS and set it and it still idles really rough. I bet you have a vacuum leak like me. If you figure out what it is let me know so I can check it on my car -=) I'm having a hell of a time finding my leak.

injector grommets, did you're injectors have them on?

well yeah i did put the t2 injectors on and thats when it really did start happening a lil more, but i dunno why it would do anything because those injectors dont kick in until a lil after 3.5k or 4k rpms.....



and is the gromments the little rubber piece (red) that goes around them???

The injector grommets are the little rubber seals that the injectors go threw. If you did not put them back on you would get a vacuum leak, all the grommets I have seen are black. They just look like a fat o-ring. What year were these injectors from?

I got these injectors from you!!!!

haha

well you said they were from a 91 but they are aftermarket so 89-91 denso's



i dont really know if it included the grommets on them

all i did is install them, took the others off an these came right on

ahah, I forgot, I sell a lot of **** https://www.nopistons.com/forums/pub...#>/biggrin.png , ok so there are the right impedence then. They are aftermarket? Huh, I had no idea. Maybe they are bigger than 550cc.. https://www.nopistons.com/forums/pub...IR#>/dunno.gif Yes I did give you grommets with them. So that can't be. Try switching back to your old injectors, that is if you still have them/if they work. Thats the easiest way to eliminate possiblites! The easiest way to check for a vacuum leak, is use a 1-2 foot piece of vacuum hose and probe around like a stethascope while its running.
