Asked by Austin Dec 31, 2015 at 04:04 PM about the 1995 Chevrolet Suburban K1500 4WD

Question type: Maintenance & Repair

I have a 95 350 suburban it's pulling code
43 i can clear it start it and it'll pull and out
30 secs later I'm assuming this is when it
reaches operational temperature and runs
the test to get a ping I have continuity from
plug to ecu it is a brand new knock sensor
brand new ignition module have 750 ohms
on pick up coil exhaust does leak don't
know if that's enough to throw it or not. I
noticed whoever had it before has swapped
ecu for a 97 the motor is not a vortex and
system is obd1 could this be a problem
