These are symptoms for what problem?

Ok, it's pretty weird. First off, I had problems with my tps. I fixed that and set at the correct setting. After my car has been off for several hours(especially in the morning), it'll start right up, and the rpms will stay at about 500-600, then it'll stabilize and idle bad ass at 800. Once it idles correctly, I press on the gas and the car just falls on its face. It won't rev but it won't die. The rpms just fall to about 400-500 and it'll make a pop sound. Once I put it in reverse, the car will start moving but at a draggin pace. Then when I put it in 1st to take off, the car won't move even if I floor the gas. It'll take about 2 -3 seconds before it pops and then it'll lite the tires up. Ok, so I get it going. Once it's running, the car will sputter in rpms lower than 2000. I mean, it'll jerk bad. If I get on the gas, it'll pick right up but it will still sputter. I have no idea what it could be. It idles fine which is the wierd part, but once I get going, the sputtering just won't stop. The throttle problem only happens when the car has been off for a while.

What do you guys think it may be?
Thanks

I would try to DL the idle and driving and see what your KAMs are. What are your inj. slopes set too and what breakpoint are you useing with the slopes.

Sounds like it could be alot of fuel in the lower rpm cause could be the maftransfer being off or slopes/breakpoint. Do you have any exh. leaks?

I have one exhaust leak at the head. I hadn't noticed it but the guy who did my tranny swap had to remove the headers and didn't put one bolt into one flange. Could that be it? I have the tweecer but haven't messed with any of the slope settings. Could it be a bad MAF? Keep in mind that the bogging goes on at any rpm.

try cleaning your maf sensor my car does the poping sound when its dirty or try a different one the maf sensor controls how much fuel is dumped through the injectors

I already cleaned the MAF. I'll try another one tho.

 

[blksn955.o]

put your stock maf on and make sure it is running the stock maf curve in the tweecer. Also do a gen. slope setting for the 30's by entering the 30 and then the 30 x 1.2 for the other slope (I get them mixed up without looking at it as to what one gets the larger number but it can be searched for quickly).

that and see if anyone has a offset for the 30's you could use as a starting point.


try this and see if the bogging goes away.

I had been running my stock MAF. I still have not installed my 30lb inj. I hope that the problem has been fixed. It ran fine yesterday and this morning. I did several thing to it on Friday night. Gave the engine more ground, readjusted my TPS, cleaned the air filter, changed the plugs and replaced my header gasket. It ran like a champ yesterday. I hope the problem doesn't come up again.
