Checked my cel codes
 

Hello everyone I just recently bought a 88 toyota supra turbo and I'm loving it so far but I've been getting the check engine light coming on for a code 51 and 52, so I guess I'm going to need a new knock sensor.What I was wondering was would a bad knock sensor effect the performance of my car because it has lots of low end torque but feels a little gutless after 4k rpm.

Anyone????

done engine work recently ?

gas mileage through the roof ?

i'd make sure the actual knock sensor's are connected .

what does the exhaust look like ?
grey
black
blue
white

when you punch it ?

I haven't done any engine work yet and the gas mileage is actually still pretty good,when I stomp on it the exhaust looks dark grey.It's wierd because the car performs awesome untill about 3500 rpm then it's got nothing left I don't know if the knock sensor would do that but I'll have to look into that and mabey change my fuel filter unless anyone else has any sugestions.I would really like to get this problem fixed before the honda's find out and start picking on me:( .
