Anubis_4_99

well i've come to the conclusion that im fucked on this build

i've replaced everything but my injectors and fuel filter and it still runs like a ------ harley

bogs any time i hit the gas, rich as hell, etc

i've tested with 4 diffrent ecu's now, and none of them has made any diffrence

replaced my wiring harness, new dizzy, etc...

everything but my spark plugs, injectors, fuel filter, and fuel pump are new...


anyone with any ideas let me know, im truely ------ stumped

Fouled plugs would do that. Are you getting spark on all plugs?

Anubis_4_99

Yeah, i am getting spark... plugs are new, but have been started on a few times and run rich.

Have a timing light?

yea, elaborate a little. A million things could cause the engine to run rough. Does it have low vacuum? do a compression test and a cylinder leakdown test. That will tell you if anything is awry inside the engine. Definately make sure the t belt is on correctly... even one tooth makes a big difference. Did you try different basemaps as well? I still cant get my buddies d15 eg to run good at all from crome. But with uberdata it rips
