so i was at walmart picking up some stuff, car was running great. so i stopped to get gas. after i started the car up to get gas the car started up with a really up and down idle. i gave it some gas to even it out a bit and the car would not rev like it should, it would just be really bogged down. so i tried to take it up to about 4.5k rpm in first gear and the turbo would just not spool, it felt really bogged down and the car wouldnt go like it should. i lived right down the road so i just kept the rpms down to make it home. i opened the hood to make sure all the IC pipes were still connected and everything looked fine. i restarted up the car and went down the road seeing if it did the same thing, it spooled a bit better but not like it should. any ideas of what this could be?

 

something wrong with the gas u put in???

 

its the same gas station i always get it from, exxon 93 oct. ive always got it from there and never had any problems. its possible that i just got a bad batch of gas.

 

i went and bought some oct boost for it, put it in and drove around for about 20 min and its running like normal again. never goin to exxon again.

 

That octane boost didn't do anything...they only boost .3 octane. So now you have 93.3 octane.

There could have been moisture in the tank.

 

The jumping idle is really common on Xs after a cold start. The extreme loss in power isn't. For fun, check if there are any pending codes with a code reader. If you don't have access to one, Autozone will read (but not clear) it for free.

Let us know if it does it again.

 

i went there and theres no codes expect the one i have from my rear o2 sensor from my exhaust.

 

the vacuum hose could have popped out on the fuel pressure regulator.

 

^ first thing I'd look at

 

checked that also. its on.

 

it takes a minute or get gas from the tank to the motor at idle speeds, so maybe something broke when you turned the car off or some a-hole at the gas station or walmart put a potato in your tailpipe when you weren't looking.

 

well i let the car sit for awhile. i just went to start it up. it was pretty bad. id hit the gas, and it would want to stall, like the fuel was being completely cut off. after the car warmed up it was fine.

 

hey did you get this taken care of?
p.s. where in florida are you from i am in the broward/dade area ... do you go to any meets ?

 

Have you changed or removed the IC pipes? What about the mass-air sensor or tubing? Basically, have you touched anything in the engine bay recently?

 

no i checked everything to make sure all IC piping and lines were connected. no problems
