Knock sensors? MFTS? Temp sender for after run pump? Oil pressure sender?
Hard to tell what is unplugged by your description - just trying to think of
things on the drivers side...

Can you be more specific - feel free to send me a pic.

thanks austin. still learning here. the bosch thing on the passenger side on
the manifold is the 02, correct? what the larger bosch thing (looks like a
big 02 sensor) on the driver's side? 

anyway - the passenger side sensor was unplugged.

Robby, 200 20v's only have one 02 sensor. Not sure what connector was
unplugged? Your torn breather could be a boost leak.

hi all,

i'm borrowing the IA3+ from ian. he's experienced the same thing with his

sometime you stomp on it and you get thrown through the back window (i.e.
fast!). other times you jump on the gas and it doesn't give you that kick in
the ass. still fast but no "pay-off" when you hit 4,000 rpm which is typical
of the IA3+.

on both our cars - engine pulls smoothly to redline. no studdering, smooth
idle. no check engine light.

my car - samco boost hoses, 034 billet bypass, new 02 sensors. i do have a
torn breather hose (just got an 034 silicone one to replace it - would that
make any difference?). ALSO, we noticed that one of the 02 sensor's was not
plugged in (the passenger side one). the connector was just dangling. who
knows - maybe the car was running super lean before and that's why it felt

we'd like to check the boost, but booth out gauges are non-operational. i
did buy another IC - but haven't gotten around to the swap yet.

anybody else experience this?
