hello every one i am having some problems with my 01 t/a a4.my car is not showing any ses lights or anything but
i lost alot of power more then a half second in the 1/4
so i took it to auto zone in the codes where p0327 p0118
p0420 p0430 are any of those really bad iknow the knock sensor is a problem i am thinking of running no cats for the 420.430 butt the p0118 engine coolant tempature high circuit could that be dangerous or expensive any help advise anything would be apreciated..
it runs smooth but loss of power low end is okay but 2nd gear is slower then my new tundra i went from a 13.5 exhaust only to 14.0 with lid bellow free ram air..

sounds like a bad ect sensor to me. It's on the drivers side head above #1. 420-430 are cat related.327 is your front knock sensor. Washed the engine with a garden hose lately?

Thats the sensor that tells the ecu the temperature I believe. It shouldnt cost much. Can codes be thrown and the check engine light not come on??

ect sensor is very easy to replace. ~$30 at any parts store.
Here's a pic from the forsale section. You can see the ECT in this pic. It's the gold and black thing in front of the #1 primary tube
