impulse nytro running ritch

[Sledneck_1987]

my nytro starts fine when cold and soon as it warms up it won't idle and surges and wants to stall under 6000 rpm once above 6000 seems to run fine. i rode 60 km today with a new ecu to rule out the ecu and ran the same as before. also burnt a full tank of fuel in a 60 km easy cruse and when loaded on my truck noticed the the inside of the tunnel is all black from raw fuel. just wondering if anyone has had this problem and what was the problem. thanks

Impulse

Just put a boostit fuel system on it and it should cured if you have fuel issues

More info. Just started doing this or has it just gotten worse. Is this a new install or have you done some work on it lately? First thing I'd check is the O2 sensor. Do you have an air/fuel gauge?

sled has run flawlessly for 2 years. did a rad delete and got the intercooler welded bc was cracked this year and now runs ritch. don't have a a/f gauge

also checked all boost hoses and map hoses and all are good.

I would check your fuel pressure. Do you have a fuel pressure gauge? Also check the vacuum line running to the fuel regulator? It could of got crimped during the radiator delete

 

[Sledneck_1987]

what should fuel pressure be on a impulse kit ????

check all vacum lines .if one is cracked or leaking it will run horrible .also check line comming off fuel pressure regulator i had fuel going back through boost referance line to throttle body regulator was leaking

Is your TPS grounded?

just through the stock connector, iv heard something about running a wire from the battery to the ground wire. you think that could be the cause ??? it has run fine for 2 years 3000 km. but i guess anything is possible
