i got a knock sensor a while ago but i never got around to fixing it ,now i also got a cooloant temp sensor on my cel.is that enough for my car to die out 3 times a week almost .sometimes it won't start.i changed spark plugs and i always use the same gas 93 BP-Amoco.what is that coolant temp sensor what does it do?

 

The engine coolant temperature sensor senses the temperature of the engine coolant.

The ECU uses this info to determine when the engine is "warmed up" and when to change to the warm engine air/fuel map.

Anyway, the fans come on automatically whenever the S/C is on. Is this your problem?

 

My problem is that when i am at a light i can hear the fan playing on and off and sometimes my car dies out.then it won't start for a few minutes but when it does it goes like nothing happend.a few 2 out of 10 times my rpm go up and down but rarely.is that part expensive.i need a whole new brake job done too 4 rotors pads and 1 rear caliper.don't know what brakes to but either any ideas?

 

For the brakes it depends on what your looking for? Regular good grabbing brakes or a higher performance setup?

I like Performance Friction pads up front. Autozone rotors all around and then whatever in the back, the back is not as important.

its your temp coolant sensor. same thing happened to me last year. it adjusts the gas when its warming up, when its broken, it will flood it and stall out. or vice versa.

THANX FOR THE INFO I WILL CHANGE THE COOLANT SENSOR as soon as i can but for the brakes,well i am a sick driver i fly everywhere.i need good not the best brakes.i was wondering about wilwood.brembo wants $100 a rotor without pads.there calipers are sky high,i mean it's a maxima not a skyline wtf.i need rotors and pads and i was thinkin about two front calipers and for sure i need a stock rear left one
