fuel issue? dumping fuel out exhaust not normal even smoky when i get on it it will dump fuel, smell like fuel and have a light tannish color
now its even a bluish/white color????? suspect
no oil is the bumper or on the ground just fuel.
fuel psi is at 40 when at oper. temp
with vac line disconnected it stays at 40psi even ?
psi regulator isnt leaking fuel out the vac line
nor do i smell gas at that line
no leaks found anywhere from the rail/injectors
pulled out cyl # 1 and 3 no fuel on plugs at all and checked compression on those cylinders
175 at cyl 1
180 at cyl 3 with 6 cranks
havent got to testing other cylinders
UPDATE TODAY I SCANNED THE CAR.
iac motor is at 62 while cruising but at 128 koeo
fuel trim 1 % -4.7 122 idle
fuel trim 2 % 4.7 133 idle
ect 196* idle
maf (gr/s) 12.52 and volts at 2.58 while idling 4.8v koeo
tps is at .647 koeo
both front o2 sensors while cruising at 35 are between 180-900mv
both front o2 sensors are reading 800-900mv at idle completely warmed up
at idle while at stop o2's go between 62-500mv
fuel psi at 43 while cruising which is good
no codes
