Put the jumper in without resetting, got code 24.
Then cleared by removing negative terminal and removing jumper. After 5mins connected negative and put jumper back in. Getting 12's now and took for a drive with jumper in. Note, my speedo does not work properly.
Still running 750-800 hot and dropping to 600-650 with lamps and heater on.
I have a multi meter but don't believe it will check the duty cycle.
I did find that the back side of the intake to the plenum was cracked at the hose clamps. Going to fix this and see what I have then.
Could this air leak before the air enters be my problem?
idle controls are dead, 600 is grossly wrong.
cracks are NO GOOD. (exactly where, rear at EGR? or Right passenger side?)
sure,. that can, crack, on mine the PO (bad guy ,hehehehe) forgot to use the top exhaust mount plate to secure the huge intake PIPE< there, and that caused its mounts (huge) to snap off. (sucking huge air)
and suck huge air, how it ran at was amazing, but was BAD.
no illegal air be allowed to suck in. on this engine. it can go lean fast. and not want to idle. (some even hunt the idle like yo0-yoo.
fix the trans cable too. it's easy, kinda. it fixes dead VSS at least VSS is super easy clicker switch in the speedo head and never fails, it. if the head end of cable spins VSS clicks.
see that maf there, facing it , no leaks behind it, but (isc, iac, TV and bleed hole) that includes injector base cushions, too.
Some ECU (fsm) shows 24 code can on some cause limphome. it even fuels using that as load calculations (speed)
hey you got easy ducks to knock over... 1 by 1.
dtc-24
VSS Vehicle Speed sensor failure , About 4 pulses per second at 25mph = normal. Detected at Fuel cut (De-Accel)
if your gas mileage is ok, 24mpg, par, then its not in limphome mode. some cars go to 10-15MPG horrible in limp.
good LUCK to you !
