car runs like crap

[wishihadatalon]

ok i bought a talon for 200. it didn't run right so i did a diagnostics check and it said it was the tps. so i took throttle body off and reset the resistance like on vfaq. did a little free mods. well it still runs like shit. around 4 grand the back just starts spitting white smoke. the guy i bought it from said it was the turbo which seems about right from the smoke and the fact that the stock boost gauge shows no boost. i figured it would show something.

i know that the stock boost gauge works off sensors so do you think a sensor is bad or turbo. and if its a sensor it would show up on a pocket logger yes/no? i am going too hook up my after market gauge on it to see. thanks for the help.

i'll give ya $300 for it.

i am almost to the point of parting it out. but i put my boost gauge on today and i got a creep up to 7 psi where it held steady. but one of the hoses that goes from my thermostat housing to the t/b came of(guess i didn't put the clam on good enough) so it started getting really hot. i never let it go past the line before the red but do you think it will be ok. oh my dad thinks i should change my fuel filter and try that.

i don't know about the filter.. DSM's are'nt famous for needing them or anything.. replace the hose.

my offer stands.

well i was going to replace the filter today but as i was backing it up i noticed it was running good. well i took it around the block. it was running really strong right up until about 5k then it would sputter a bit. a friend told me to check ignition timing. so i will probably do that

sputters...sounds like the blow of valve.

probably not unless he is venting,or his flange is cracked or the like..

well it was running right. not anymore. changed filter nothing. but it sounds really rich. backfires in between shifts. i don't know what to do. i don't understand how it can go from good to bad in one simple drive.
what happened was, i was out with a friend and at about 5 grand it would sputter well he said maybe it was backfiring and i was having trouble trying to figure out the firing order so i switched the 4 and 1. it ran like craps so i switched them back and it started running like it did when i got the car. hasn't ran good since
