i am pretty sure that is where it is coming from, i had a mechanic tell me that could be the problem, but he was a tranny specialist so imnot so sure of taking his word. but anyways the popping sound only happens when my engine is ice cold and i give it gas without letting the engine warm up fully, the engine fully warm only gets to be about 160-170 degrees max, even if im flooring it all day. when the engine is cold, i start by giving it gas and it is real realsluggish, i need to put my foot down a good distance before any power can be felt, and as soon as i get past 2000-2500rpm range it all of a sudden kicks in power. the popping noise only happens when i give it gas. any ideas? i bought the car used, it has 110,000 miles, flow master cat back, msd cap and rotor with ford motorsport 9mmwires (the cap/rotor and plugs and wires i had put on 2 days ago, the sound was happening before that) and a mac cold air intake. to finish it off. the engine never backfires or pops when it is warm. any ideas would be greatly appreciated. thanks

ok cool thanks, what do they stand for? sorry im a little slow....long day trying to figure out what this noise is

You might want to check your timing

my timing was at 8 degrees, and they advanced it to 12, stock is 10, and the noise was happening before that anyways....

I like the way your car looks without the luggage rack, remind me to do that to mine when i get back.

timing, ect, act, THERMOSTAT... you car should reach atleast 180-190 degrees to run properly..
also check your O2 sensors

haha yah it looks cleaner without the rack on....but looks are nothing when my engines popping.....[X(]

89TripleWhite

well my timing is at 12 degrees now, and it still pops, i have back O2 sensors i had it checked, thus my check engine light being on, what does ect or act stand for?

Sounds to me like you got a sticky substance causing your lifters or valves to stick. As the engine gets hotter, it would make sense that the stuff would lose its sticky quality and free up the engine. Rather than constantly wasting your money trying to figure out what the problem is like i did, take it to a local mechanic and see what is the problem. Chances are its internal and needs a little bit of deconstruction to get to.
