It started this last year when it got cold. No matter how warm the car is, at times you can press the pedal to the floor and the car does not want to move, RPM's SLOWLY increase, sometimes it will backfire through the intake. Then all of the sudden its like it will "cough" and the car goes fine. Any thoughts??

have you tried the timing , it could have jumped time .does it drag or anything when you try to start the car ?

It feels fine. it idles funny and stalls a lot when it gets cold out, but nothing has changed and it never does this when its warm out. last i checked it was at 14 degrees

come on, SOMEONE else has to have an idea of what is going on??

You can search and search, but there is not alot of advice for this type of problem. Ironically, this problem happens to alot of 5.0'ers. You can check the DIY section that includes cleaning the MAF sensor, replacing the TPS, etc. Some people have had success changing out their O2 sensors. However, if you do find the culprit. Please let us know so we can better answer the next person who comes along.

Yeah, so basically start kicking out the cash replacing stuff that might not need replaced till i figure it out lol. I guess i have to start somewhere

I had the same problem when the engine was cold (slow rpms, coughing, back firing through the intake) found out it was a vacuum line that had come loose, problem sloved.

no it's called run a koeo/koer test and see what the computer sees if anything...if no codes come up..buy some maf cleaner and clean the maf

is this a test you can run or do i need a code scanner? this is irritating to the point i hate driving the car if its cold, so its time to fix it!
