Hello, I have. 91 with a 351. It's come time to replace some sensors like IAC and TPS. So I figured while I'm in there and working on stuff I thought that I would take off and clean the throttle body and put in a new throttle body gasket. My problem is that I don't have very much experience with throttle bodys. If anybody has some advice to share. Or has a good web site or video that could help and could give me a link to that would be greatly appreciated. Thanks in advance!

what is it you need to know?

Mostly just how to clean it. And if there any tricks or hints or things that I need to look out for

just pull it off...remove the TPS and IAC...blast it with throttle body cleaner... you can use a soft toothbrush if needed...let it dry ...install your new parts and re-install...not hard at all

Okay. Thank you very much! That's exactly what I needed to know!

A new TPS and IAC will run you $80 or so...depending where you get them

Yup I can get them both for about that at my local auto parts store. So I figured for less than $100 I should just replace them now to save from any problem later on

I would and had too...

OMG It Runs

I just took all the sensors out and dunked it in a bucket of carb cleaner. Unless the bypass holes are clogged or the butterflies are carboned up to where they won't seal up well its not going to make any difference anyway really to clean it.
