i swap a6 IM, double stack spacer onto my a1 engine about a week an a half ago and today i start the car just to warm it up and once its warmed up, it stayed in 2000rpm and wont go down. also i started to see white smoke coming out of the muffler and went to go check back there and i can see some sort of liquid coming out. its cleared liquid but didn't taste it to see what kind of liquid it was. it look almost like water. i see no leak under the car or around where the runner meet the whole engine. what could be the problem? starting the new semester on the eleventh and need to find the problem.

DO NOT TASTE IT.
White smoke is coolant. It's often the sign of a blown head gasket. If it's just at startup, then it may not be coolant. It may just be condensation. The smoke is steam, and the liquid is water. If it continues after the car is warm, or gets worse when under load, then it's coolant without a doubt.
There's really nothing with your intake manifold that should result in burning coolant...
As for the 2000rpm idle, go to the DIY section and read the "sticky" threads made by HondaFan81.

thanks, to make sure its not coolant i should take it out for a test drive and see if the car still have water leaking? also can it be the gasket between the runner and the block or head which ever one its bolt up to. oh yea one more thing when i did the swap i accidentally messed with the bolt on the cable that was attach to the plenum. could this also lead to the 2000rpm idle and i'd tried doing the base idle setup but car either turn off completely or idle between 2000 and 3000. but once under 2000 the rpm goes up and down.Comment

Yes, that cable is your throttle cable. If that's too tight, your throttle plate won't close. That would most certainly result in a high idle.
The surging idle fix is in the threads I mentioned, as well as the "sticky" threads in this section. I strongly suggest you read them so you have an idea of what you're doing.

sounds like head gasket to me u could check your coolant level.. as for u messing with the throttle cable idkComment

coolant keeps on disappearing but not leaking to the ground. put a card board under after warm up an hour later i came back to check, its still dry. so it is my head gasket going bad and also forgot to put that my car overheated a few days ago on the way back from pick n' pull. had to tow the car back home. im going to take the car to my mechanic and have him put the head gasket and all the other little o-ring and sealant that came with the head gasket set. i was just wandering is there any other better brand then fel pro gasket or is fel pro good enough. just asking to see if there any other brand that is better then fel pro. thanks guys. oh yea the throttle cable ima let my mechanic adjust it and set my base idle for me. and sorry one more question. after the a6 swap i bypass the line for the butterfly to the back of the plenum and after starting the car the butterfly stayed open. is that normal?Originally posted by jimbo34 View PostComment

The IAB is open when it's not on vacuum, I believe.
FelPro is alright. The only other option is to go to Honda and get OEM Honda gaskets. FelPro should work well enough, though.
if the car overheated, then you most certianly blew your head gasket. You may have also warped your head.

Yea felpro is good and probly cheaper then dealer gaskets.. after the fix keep an eye on coolent lvl and white smoke after its warmed up or any leaking for the next few days.Originally posted by splitsecondcb View PostComment
