Poor Acceleration!!!! Help!!!!

[terbo]

I don't know what is wrong with my talon, It ran perfect, then a couple of day's later it slowly started to run like crap, in 1st gear I have to rev the hell out of the engine to get the car to go with out stalling, and keep the car in a high gear to keep moving or it stalls!
sometimes it does stall and then if I try to start it back up, and give it gas it wont start, but If I start it and don't touch the throttle it starts and idles barely, then I start the whole process of keeping it running again to go anywhere. it only seems to do this if I want to go from a stop once it's going it's fine, it will stay Idling, unless I rev the engine and let off really quick, then it stalls. This seems to be some type of accelleration problem, and I dont know what it could be. my air/fuel meter used to always have some thing going on, now when driving it does'nt give any readings.

I also went and checked the plugs to see if they where bad (iridium 2weeks old) and 2 of them were wet with gas, and the other 2 were dry? every other one from left - right.
could this mean any thing? I checked for spark and fuel, and it's good.

please any help suggestions will be greatly appreciated!!!!!!

Compression test... Headgasket might be blown

 

[terbo]

I did do a compression test and my cylinders shows 115/125/135/135

I also have a data logger and it does'nt show any error codes, so It must be something non sensor related. what do you guy's think?

does a data logger show compression? or only a dealership can do it

mitsuclipsegsx- You can do a compression test yourself - you can pick up a compression tester at most auto parts stores - Compression Test - Step by Step - you may want a friend to help you out.

terbo- Are you getting any knock? If so, then the ECU could be retarding your timing and thus making the car incredibly slow.

Judging from your comments about your a/f readings, your o2 sensor might be dead. If its not reading anything at all, that'd be a pretty big clue. Iridium plugs aren't gonna be of any real help either, you'd be best off just buying the stock NGK copper ones and save you a little bit of cash.

I'm not getting any knock, the car as if a interccoler pipe is leaking, but it's not the case cause I checked them, the head gasket thing is what I'm leaning twards. If I try and drive the car normally for 30 min or so, my exhaust mani glows like it's running lean.
my a/f gauge is back to normal. there is another thing I forgot to mention, a couple of weeks back I was getting a loud clicking noise from around the crank area, and found out that the bold with the square insert in the middle of the crank was loose, I tighten it back down. my car started to run bad around this time.
