i've got a stock ecu with a new intake manifold and a new throttle body. there are no vacuum leaks anywhere and im getting an irratic idle. i think its because i need to have my ecu remapped... its got other work to it. maybe its just time to upgrade the ecu... please help

 

its not the ecu, check the idle control valve... and recheck for vac leaks

 

vac leaks are def out of the question, i've got so much rtv on the thing i could throw it to the bottom of the ocean and still be sure. do you have a screenname or something cause im still on a trial version, i only have 3 posts left for the day

 

bump...please help...

 

as in new intake manifold do you mean aftermarket? if so it might need a tune b/c more air flow causing throttle and maybe idling problems

 

yes aftermarket manifold and throttle body all skunk 2 racing . i have ONE post left, im a new user, PLEASE IM ME AT FORUMYNGBLD159 @ AIM.... some shop said check the throttle pos. sens. but i think its ****, it fits fine and i dont think its irratic enough to be that, im gonna clean the idle sensor now, ill make a new name and keep posting.

 

Bump ! come on people, i need my car today, help me out!

 

First off, don't bother bumping your post after 30 mins. People are reading it, they just aren't posting, maybe because they don't know what to reply.

Now some advice. Take off your intake and look and listen inside your throttle body. I had a Skunk2 TB that leaked air in past the throttle plate that was effectively a vac leak because throttle = 0% but too much air was coming in.

 

What engine are you running? Also you should use a throttle body gasket and not RTV or RTV and a gasket. Take off your throttle body and clean off all the RTV so its nice and shiny and then put on the proper gasket.

 

check for leaks in your intake manifold gasket, make sure it fits and seals right. that was the problem with my DA and an aftermarket gasket. turn it on and spray it with brakecleaner to check for holes and leaks. if not, its the idle control valve on the backside.

 

WHy aren't you using OEM gaskets again? Also check the throttle cable as it maybe to tight and the trottle could be stuck open.
