The story continues with my Caddy but I figured a new thread was appropriate. Put the MCS screw in the carb back to 1 1/4 turn, just like I found it. Measured the IAB per the service manual gauge spec, and set it as close as i could without the unobtainable gauge from GM/Thexton... Fixed bad plug wire, drove it yesterday and it ran great, except for a code 34.... My 44 is now gone and no drivability issues, idle was good, with a very slight hiccup every once in a while, hardly noticable.
I replaced the air shocks yesterday afternoon and figured I'd work on the code later, since it was running well. This morning heading to work, it starts, and runs great until about 5 milles from my house, at which point I am getting hesitation/lack of power and what sounds like backfires. loud pops and a hesitation. I'm on an expressway at 55 to 65 mph at this point.... No power on an incline, but if I really put my foot in it, it will accelerate somewhat. Then, the pop/hesitation again...
This one has me stumped, as it has never backfired/popped before... I can't find any vac leaks, the hoses look good, everything is hooked up.....
Any thoughts, folks? map sensor maybe? (the manual calls for a scan tool to check the voltage for that, which i do not have...) I'll triple check that the plug wires are in proper sequence but i am sure they are..
