sr20det engine problem

**SeamieB** · 03-05-13, 10:05

Iv fully rebuilt an sr20det recently an car has covered 3000miles since was refitted.. in the last week the car wont take the shoe at all and will boost fully but no go in the car at all, iv checked all boost pipes and intercooler for leaks, tested fuel pressure, cas etc.. one thing i have noticed is car when is cold it revs up close to 1800rpm an after afew seconds drops back down to regular idle and when cruising at 60mph the car develops a slight misfire every now and again!! anyone have any ideas what it could be? timing issue etc?
