The 4.0 throttle body came in today and i put it in. I also ordered a new gasket that goes between the throttle body and the engine and i am glad i went ahead and ordered that since it was only $1. My old throttle body was nasty. The whole inside of it was black and gross, and the used one i bought wasnt much better. But theres nothing like some good ole' elbow grease to get it cleaned up, and......also some throttle body cleaner
So heres how i did it....
first i disconnected the negative wire from the battery then disconnected all the wires going to the throttle body.
Next, i disconnected the pipe going from the air filter to the throttle body and put it aside to get it out of the way.
I then unbolted the 4cyl throttle body and took all the sensors off of it.
I cleaned the 6cyl throttle body with carb/throttle body cleaner untill the inside of the throttle body, the part that the air travels in, was nice and clean. I also got used an air hose hooked up to a compressor to get all the dust and dirt out of the valve and in the nooks.
I took the sensors off the 6cyl throttle body and put the ones from the 4cyl onto it.
I put the 6cyl throttle body up to the intake and traced with a sharpie where i need to trim to make the hole bigger for the new throttle body.
I got some paper towels to put in the intake and got some painters tape and put it upside down on the paper towels to catch all the metal shavings, and got the dremel out and started grinding it out.
Then it was ready to go back in.
I put the new gasket in, bolted the throttle body up and hooked up all the wires, connected the battery and was finished.
AND to top it all off, I went to start it and it started up no problem on the first try
....that doesnt usually happen haha
