i just installed the icebox yesterday and now i'm left scratching my head. when i accelerate, it really feels bogged down. i have already driven it for about 2 hrs. so the ecu should've already read the change. after the last spin this morning, i got back home and it really started doing this noticeably bad idle that u could see on the tach and hear the muffler sputtering.

one thing i do know i didn't do is replace any coolant. i spilled quite a bit but then the radiator looks full. all connections have been triple checked. your advice is appreciated.

 

sounds like you have a vacuum leak ...your idle will bounce in the ecus effort to control the idle rpm...i would check things like make sure there was no packing meterial left in the cone,and that all the lines are re connected if all else fails try the idle learn procedure

 

the one step i will do again is dis- and reconnect everything. and what is this idle learn prcedure?

 

look in the fliter for packing material and in the tb...the idle learn can easily be searched but basically it's disconnect the neg battery terminal 15 minutes is good...hold at 3k until both fans come on then allow to idle...not 100% but do a search,been covered many times

 

This may seem like a stupid question but you never know. Did you remove the plastic from around the filter?

 

A vacuum leak wouldn't nessesarily cause an issue under load. Normally it is just at idle or high vacuum situations. Under load there should be close to no vacuum.

 

i didn't remove the plastic. haha, why of course!
oh and thanks to type r for mentioning the idle procedure. i searched that bitch and got tons of answers i didn't find before. that seems to have worked. hopefully other noobs will read this and not post these kind of ?'s for a while.

 

 

has anyone else experienced their car shift before redline between 1st and 2nd? normally on WOT, it would reach the redline, but now it just reaches 6,500 rpm.

 

when you reset the computer that will happen...go WOT a few times and shifts will come later and later

 

Undocumented adaptive shift algorithm.

Do what typeR mentioned.
