So i went to check the tps and i found this green plug (what i think is the tps) and nothing for it to plug into. I also found a yellow one. Can anyone tell me what these plugs are? Heres a pic

I can tell you that that is not a tps plug, the tps is located on the throttle body. I have no clue what those are for, could be for stuff that your car doesn't have

I believe the yellow plug is the fuel pump jumper plug, don't hold me too it though.

The TPS is on the throttlebody, follow the air i take tube up to the TB, than look a inch or so past that, on the side of the TB there will be a flathead screw with a spring part of it, thats your TPS adjustment, just folloe the wire down and theres your TPS plug

Nvm, i see it hiding. You'll have to look at the FSM to see which wires you need to use, ii'd say but don't remember. I think its G/R and Y

TPS has been adjusted. Can is running much better now, still some afterburn(backfiring) and that slightly effects the idle. What should I do about that?

did you clean your BAC valve yet? shouldn't have much of an effect on anything but idle. Also, you have it timed correctly? You haven't turned the little **** next to the pressure sensor have you?

Will I have to drain the coolant to take the BAC off?

You can drain some, not all is necessary. If you want you could just pull the lines off of the bac, and drain there.

After a while the idle smooths out, but everytime I rev the motor on the way back down to idle it afterburns again.

Just out've curiosity, you said your compression #'s were good. What exactly were they? And you performed it up to normal operating temp right?

I didnt do a proper compression test, just the way there you remove a spark plug and check for air.

K, time to start over my friend, borrow/rent a compression tester and do it according to the link provided on the first page, than let us know.

Just cause it "sounds" good, doesn't mean it is
