Will cooler weather affect my tune??? or mainly my idle??? Ever since it has cooled off a litle, my truck will surge and buck, try to shut off, and sometimes does....
Any input will be appreciated fellas!!!!


thanks
Brian

 

My truck runs considerably better in cooler weather. Not sure why cooler weather would make yours run poor.

 

It runs awsome, its just when it tries to idle is when it shows its ***...
bucking and shutting off and stuff

 

is it throwing any codes yet?

mine did this a little when my IAC needed cleaning really bad

i just grabbed some 3M throttle plate cleaner and went to town

 

No codes, I will try the IAC idea, didnt think of that!!!
thanks

 

Also check your MAF , could have oil on it from the filter. Clean it with some electrical contact cleaner. Let us know what you find.

 

I cleaned the throtle plate and the maf contacts.... I think it does it more after it has been sitting a while... I started it up after work today,after sitting in the same spot all day, and let it run for maybe a minute and 1/2. well I had to shut it off and go back in the shop, came back out fired it up and didnt have any problems....



Thanks guys for all of your help and ideas!!!

did you remove the t/b and clean it all inside and out take the iac off and clean the port with a q tip?

my throttle body is DBW, doesnt really have an iac motor... but the tb was pretty nasty...

 

How about the TEMP. sensors ? Maybe one of them is out of range .
