hello guys. well i'll give you the background. my fd has a rebuilt motor 1k miles ago, microtech ecu, intake, downpipe, catback, koyo, and fmic. on saturday i was driving it down the beach and when i was on it i was noticing some smoke behind the car. today i noticed a stutter like the old 3k stutter, but not as bad around 6.5k. then after driving it a little while tonight the car doesnt have much power at all under 3k and its kinda breaking up and stuttering when ur driving under that rpm. it almost feels like it is starving for gas. it is almost on empty, but i have run it lower. i know ur not supposed to boost under 1/4, but ive drained my tank a few times, so i do it. anyway, i guess i am hoping for a quick answer like x hose popped off, common problem. if its not a problem anyone is familiar with, do you think it is safe to drive it to the shop tomorow morning about an hour away? the oil pressure and level are fine, and its not overheating, or smoking at all. thanks for any input.

Well number one don't be cheap and stupid, go and put more gas in the tank! Its a lot cheaper than killing a seal from being starved. Number 2 what color was the smoke that was coming out. You didn't really provide enough info.

 

mostly black. maybe some white. it was also idling real bad after it started running bad tonight. it was idling at 100 rpm at one point.

 

do you have a boost gauge to see how much vaccum your pulling?

 

Sounds too rich to me..... You should take a look at your microtech settings. What was the 02 sensor voltage??

 

i do not have a boost gauge. and i have no way to look at my microtech settings. i am still waiting on the software. it was tuned professionally, idk why the settings would be changed.
