running BADLY and rich

[DSM-ICELAND]

Well to begin with this engine assembly has been an one rocky road!?! Well started my baby up tonight and the engine reved itself to 2500rpms or so and then dropped and stalled...

tried starting it again but it wouldnt keep running by itself, i had to keep tapping the throttle to keep it running...then those massive kinda unburnt eye soaring fuel fumes filled the air and made my realise it was running WAY to rich...so I tried adjusting it with my SAFC and my maf translator but nothing seemed to work...tried messing with the BISS screw to try to make her run with out any extra "help" but still it stalls and also made my think my 272´s I just installed might have to be degreed..are they?

I also took a glance at vaccum connections at the; fuel regulator,TB and EGR and saw nothing wrong at first glance...

What is causing this massive fuel mixture and why the hell cant I fix it with my piggybacks..

p.s. I was just informed that the ECU in 1gens tend to take their time when making new fuel trims and maybe I wasn´t taking the time that i´ve should...

Any advices or ideas are so gladly accepted Wink

Sounds like a large vacuum leak or that the timing is wrong mechanically.

do you have a afpr with that 255 i didnt see one in your profile. trust me you will run extremely rich w/o one, i had raw gas coming out of my exhaust before i installed my afpr.
might not be much help but this is all i can think of.

Yes it turned out to be a massive leak between the intake manifold and the head and after I replaced the gasket and sealed it the car kept running by itself finally...still it idle surges a bit so there is still a leak somewhere...and Im running a stock fuel regulator ### Mark at SBR told me it wasnt important to change it out until I was going for 500whp...
