First off, making another thread titled "come on guys can I get a little help with my other thread" will not win you any favors or get you any help, in fact if you keep doing it, you will find yourself removed from the forum.
Second, maybe you should try and type in a manner that people can understand, go ahead and use all the letters on your key board. If it takes me extra time to try and de-code text speak, or really poor typing, I move on, and I know most of the other guys do the same.
You have not done a very good job of describing your issue. What mods does the car have? Stick or auto? Miles? Where is the timing?

I have nothing to contribute besides lol

im just desparate.. it has cai,full exhaust,gears, underdrives, and its a 5speed timing is good and like 165k. but i have a major loss of power my tack surges,and when im running my gears it strugles to get to 5k rpm, i have replaced the tps and iat since that first post

well how do you know the timing is correct? have you checked it? how did you check it? was the spout disconnected when timing was set?

and it does kind of sound like a vacuum leak. how do you know for sure you dont have vac leaks? have you had it smoke tested? have you actually checked the vacuum?

also did you do anything to the car before you noticed this power loss? or did it just happen? think.

we need more information really. since we are NOT there to look at your car, YOU need to describe the issue as best as you can, giving a lot of info.

no i didnt do anything just happenend... and yea put a light on it.... and like over all it has no power. the tack surges back and forth while driving. and its like i cant get it above 4k like its leaned out.... and i checked all of the lines... but smoke tested whats that??

nacanitihs

"put a light on it" im assuming you used a timing light but did you disconnect the spout connector when you checked it? otherwise it will be wrong. with the spout out you want it to read 10* BTDC at idle

a smoke test is just what it sounds like. blow smoke over your motor to trace a vacuum leak. the smoke will be sucked into the area where the leak is, thus finding your leak.

but from the sounds of your problem it does sound like you have a vac leak or the timing is set wayy too low.

also, did you set your TPS correctly? at about 0.98V? you set the voltage using the green wire and i usually use one of the screws for the ground. dont worry about what the rpms do when you set it. they may go up, but when you shut it off then restart it you should be good.

and what do you mean iat? did you mean ACT or IAC?

by iat i believe he is reffering to the air temp sensor in the induction tubing! on your fox its in the #5 runner.

Have you checked fuel PSI, how old is the fuel filter?

jeb94stang

fuel filter is new.... and fuel pressure was 2 or 3 pounds low
