Cold weather

[jonbacon]

So, wondering whats wrong now. My car drives fine in the warmer weather..it is basically acting like it has a vacuum leak. But like today when the temp is up almost 20 degree's it drives perfect.. no leaks or issues tps and idle are great.. but when it turns cold it acts crazy and loses power while driving..kind of surges, acts like it has a leak, or tps is off.. but all is good and cranked up and drove great today.. it drives bad when the weather here gets below 60??

any idea's?

Dump the codes and see that the computer thinks is wrong. Codes may be present even if the Check Engine Light isn't on.

See the "Surging Idle Checklist for help with all your idle/stall problems. You can guess at the problem and throw parts at it, or you can use the checklist to help you find the problem quickly and inexpensively.

The quick and easy way to dump the codes is in there too, and all you need to do it is a paper clip! The first two posts contain all the fixes & updates. At last count there were 24 possible causes and fixes for surging idle/stall problems. I continue to update it as more people post fixes or ask questions.

Ive done that jrichker,twice.. no codes even on manual check. It drives fine on smei warm days. But when it turns cold is when she acts up.. I have no codes and it could be the air filter, has a cone on it now.. wonderign if the stock box may help..I went through all the list since i had all the other issues last time, didnt want a repeat . but everything is good and even drives good untill it gets cold..it will drive fine for a minute or two then just starts to act like the pvc is unhooked ..just loses power..very annoying..
