SR20det boost hesitation

[j_aguilar88]

hi i resently swapped an sr into my 240, it was fine until this really cold morning i started it but it kind of like hesitated but dissapeared after i left it on for around 5 minutes, then when i started driving it i could feel it hesitating again when its going into boost, i cAN go into about 3psi as long as i dont slam on the pedal hard and keep my rpms at around 3500-4000 then it hesitates, i try not to push it to prevent detonating but i dont know what could be the problem. help will be apreciated

thats kind of a vague description. how cold was it outside when this happened? and what exactly do you mean by hesitates? are you using a stock ignition system or did you switch to a distributor? how full was your gas tank?

[j_aguilar88]

stock ignition system, just exhaust and walbro fuel pump, it was about 12 degrees outside when it happened, as it starts going into boost it goes up to around 3-4 psi then it feels like the car falls on its face but then grabs again but kind of hesitates again, i dont want to push it hard because i dont want to risk detonating.

well you could do what we do to check for leaks on tires... get a spray bottle.... pour some liquid soap in it and fill it with water. spray everything thats gonna be under pressure(intake, cold pipe, hot pipe, intercooler).. and check everyclamp ( i double clamped everything on mine) run it... boost it... and check for any bubbles on anything you sprayed down.. and spray generously. even check your bov for a leak. also make sure theres not extra air entering the motor thats not read by the MAF
