Throttle Body/Throttle Position Sensor

[3Waggintails]

OMG!!! My brain is fried.  I read and read and read your stuff.  It is just over my head in many cases.

I can read and comprehend but I just get lost in all the jargon, etc.

A)  first of all,   Is the the Idle air control valve shown in your picture you just set?  See link below

You are saying that this can be cleaned.  Can it also be bad?  what test will show if bad - vacum test?

This is the thing that controls my correct 800 RPM idle?  It can be dirty or getting bad message from TPS?

I am trying to make sure I understand in simplest terms.  I have to read your responses over and over and over again because I just get lost....

FYI:

This is throttle body I got off ebay (should be correct for my 1997 car as opposed to what originally on my car):

This is modulator I got off Ebay:

This is VSV switch I got off ebay:

This is EGR I got off Ebay:

I work really hard to get the right parts and ask a lot of questions, etc.  As you might guess.  LOL

Just want you to see parts.

B)  I could not find it in your response but my brain is just dead over this....What about the O2 sensor in the down pipe?  You think dead for sure?  You think possibly leaking air around that if not a crack in the exhaust manifold where you indicated or both?  I need to know so I can have them check all.

c) You did not say whether you thought my idea of putting all parts back EGR, MOD and my original functioning EGR switch was okay.  They are all good.

d)  Should they put back the ORIGINAL throttle body and TPS from my car (even though a 95 model TB/TPS) or leave the one I got off Ebay from 98 tracker (one that should have been on my car) on there?

Is there a possibility the switch part in the TPS is dead/ no good so would need new TPS anyway?

E)  So I could need a MAF as well pending testing?

f) MAP only for EGR - correct so doubtful I would need?  Only find used that not arm and leg unless you have source?



I have to go there in the morning tomorrow early so I need to know.



Not to mention, I need to return parts. I cant keep stuff I dont need and $$$$ will help pay for any other parts or toward possible more BILL with them.

I have to contact Ebay for extension on TB return and I can return a $150 TPS to Advance if I am keeping my original throttle body.  Need want respect what you have to say on TB/TPS situation.

I will try to go through all your responses and make a list in rank order for them to do:

1, 2, 3, 4, etc....if I can figure that out.

Also, would any pictures of engine etc be helpful just for the record?  If so what would you like and I will try to get?

Please ADvise ASAP.  

Are getting PM's that I am sending?
