1st sebba LMAO hahahha..how u want it lmao..but um..well yea it might be the fuel pressure..the guges goes to 20-40..and the regualator..how do you set it or w.e? but yea that might be it..but will that make difference in warm or cold weather? THANKS for the help guys..

 

im assuming that you bought the car like that?

 

The fuel pressure should be at about 45 at idle... i crank it up a little. There should be an adjustment screw on it.

 

were is that cause in my mustang its just right therebut this one aint lol...but yea wel i also have the DSMLINK thing also and another laptop just for it..so it has it on there..but im not to sure how to mess with it yet...i went to dsmlink.com and read but with my car built i dont know weree i want stuff u know..so you know anything about that? thanks alot bro..

 

Okay, try changing your spark plugs and your spark plug wires.

Use ONLY ONLY ONLY (clear?) NGK Spark plugs. NOT the iridium ones, they suck.

Change your spark plug wires with Mitsubishi Wires. You might have to get these through a dealership, but trust me, they are better than any aftermarket stuff.

 

Nevermind, you have coil on plug. Make sure all the connections there are perfect.

Check the gap in the spark plugs.

 

damn, not trying to offend you or anything, but it sounds like you bought something that is way over your head. Just my first impression. Nice setup though, the person that owned ti definetly had some money to build this thing

Now i agree with sebba, this definetly sounds like a fuel pressure issue. I think its probably dropping off and thats why your having trouble after its been sitting for a while

Also could be a tuning issue with such an aggressive setup.

Another possibility (although small) is a fualty coolant temp sensor or wire going to the sensor. Just something to look into

 

It may just be a characteristic of that setup. I mean, like TE said, its very aggressive.


So if it turns out not to be any of the above stated things, it might just be normal for what your running. I can see it being a little rough with high lift cams on there.
