hey all man im geeting tired of this car i might just get a carrera 4 **** lol but i dont think that i can get rid of my 7 well can anyone help me with this, i have checked the fuel cable and it has play in it so thats not it, i check my hoses and couplings and there all tight, i have adjusted the idle screw so im lost oh yea amd my airpump is out was told that could be it but i plugged that line up too

 

maybe a cracked UIM, or maybe a bad UIM gasket??

 

Have you rechecked the TPS?

 

Had the same problem, and it was a combination of both, a cracked throttle body, and a misadjusted TPS.

Damian, has a good thread on how to adjust the TPS. Just search for it.

 

Don't forget the Air bleed screw too.

 

how can you tell if your uim or tb is cracked i mean do i see smoke or air leaking. i just swapped out tb and uim so please let me know

 

and guys what is the tps and were is it can someone post a pic

 

get a can of carb cleaner and spray it on the UIM and around the gaskets, if the idle jumps up or down, you have a vacuum leak somewhere, and make sure that all of the vacuum hoses are connected to the nipples.

TPS info....

 

Did you check your TPS as I recommended you do in the last thread you posted about this?

Here is the link again to what happened to my TPS when I adjusted it. Additional info can be found on the rob robinette site.

if you can afford a carrera 4, i would suggest you to get one. that or just pay a professional to fix it since you got the money. its not worth the time or effort on your part if you can make just as much money working to tell you the truth.

 

this is a good idea although i would suggest starter fluid. just have a fire extinguisher handy just incase
