Running WAY!!!!! to rich

[lowlux]

Im having i think a spark problem or a overfuel prob,when i rev it out to 5000rpms its shudders and sounds like its farting lol, but 5mins ago it got me really scared as the leftover fuel in my muffler cought fire and i had a fireball out of my exaust for about 30seconds lol now does any1 think they know the prob,cause this is getting ridiculous. Im thinking it could be the oxy sensor but i thought it only works when idiling, or what happends when the car is cold? is there a sensor that tells the ecu when its at running temp and uses less fuel??? please help

also with timing on the rb20det which way is what?

cause my cas is like over to the anti-clockwise direction almost as far as it goes, but on other cars i see its around the middle?

could it be timing???

are you still running an AFM, i have had a similar problem due to a faulty one

and the other possibility could be a leaky injector

hmmmm yes they could be a possibility but i want to rule out the timing first and ive tried like 3 wires with the timing light and they all come out different lol

get a timing light for one.... check she about 11degres ret... if you dont know what that is just go and get it done... No big deal...

Then if you can offord it get an apexi safc as a replace ment AFM brand new is over $800... Trust me i bought one.....

Put a coil pack and spark plug in the exhaust and do it low-rider style . This is the kind of shit you want on your air bagged ute

ive got a timing light but u said check its 11degrees retarded??? isnt it spose to be around 15degrees advance? lol and al my exaust on my hilux sits under the tub so the only flames its gonna shoot out will be at my bags lol and i dont want them bursting,cause thats scary when that happends when driving
