i just recently installed a skunk2 manifold on my 94 gsr motor. i have a 97 ek.

since i installed this, my vtec stopped working. i checked my CELS and i got 6,10, 54.
6- IAT (intake air temp)
10- ECT (engine coolant temp)
54- CFK (crank flunkuation)

i know its not 6 and 54 because it doesnt effect vtec. i checked my ECT and its the right plug and everything. could it be my ECT? how do i fix this? my temp on my guage cluster still works so i dont know if it has anything to do with it but yeah can anyone help? any suggestions? thanks.

 

VTEC has to be at a certain temp to engage. If you dont replce the ECT, your car will have a hard time starting when hot. There like 30 bucks at NAPA. I had to replace mine. That is probably your problem.

 

so even tho my temp on my guage cluster works i still need to replace it? how could it just go bad after changing manifolds?

 

anyone!!?!?!?!

 

I would check to make sure it is installed correctly. Look for pinched wires, or loose connections, or air in the cooling system somewhere. The temp gauge runs off a coolant temp SENDER.... simple thermistor, and the ECM (vtec) uses the coolant temp SENSOR.... they are different.

 

ok so where are these sensors? if im right theres one below the dizzy that looks like a nipple and the other one you just have to follow the bottom radiator hose and its a circle plug. let me know

 

The one below the "dizzy" is the temp sender - that controls the gauge. The other one is the sensor.

 

ECT Sensor is on the left side of the head right in front

 

switched the ECT sensor about 10min ago, wasnt the problem. any suggestions

 

caveman, can you explain exactly which ECT sensor you replaced? there are two. which one was it?
