    Does this thing get driven often.?...I have OBD1 in my '38 and I only use it for timing adjustments...It's a great system 'cos of the minimal control the ECU has over the engine...I always disconnect the battery when it's parked in the shed "that's most of it's time" and it does a real quick re-learn on the tune when I can get the time to fire it up..Does yours have a "full lean" in Park and neutral.?..The Bosch system in my Chevy does...Very loud sucking noise from a pod filter gives it all away..But I do have an improved memcal in the ECU...Plug and play deal...Adds fuel and timing and no CEL.

      +ZIGgassedUP Its been sitting for 3 months or so. I am not sure about how lean the ECM wants to make it. These TBI engines do not have a vacuum adjustable fuel regulator so its always too lean, or too rich at idle. I was also thinking because it sits and its hot here the charcoal canister could be loaded up with fuel vapors from the hot gas tank.

    I have a 1994 GMC k1500 5.7 that has been running rich since I bought it. I have bought a brand new throttle body that came with the new injectors and idle air control valve as well with the throttle position senser. I also put a new temperature coolant sensor in along with a new o2 senser and mass air flow senser. New starter and plugs with wires as well as a cap and rotor. All of this has been done in the past week and it's still running rich. I did pull the plugs to check them again and noticed that my # 7 and # 8 have black sludge look to them. So I have just bought a new distributor and will be installing that Friday as well as doing the timing. If that don't work the only other thing I haven't replaced is the EGR valve. Any input from anyone would be helpful thanks.

    • @GhettoWagon
      @GhettoWagon  3 роки тому

      There is no mass airflow sensor. If its running truly rich check the fuel pressure could be dripping fuel injector could be too much pressure from a messed up fuel pressure regulator or someone messed with it raising the pressure. If one plug is fouling could have a bad valve seal. Valve guide and its fouling it with oil. EGR valve wont do anything. I dunno why so many think the EGR valve causes so much. Its only used at part throttle to mix exhaust gasses in to lower combustion temps and clean up the tail pipe emissions. When mine was broken from a ripped diaphragm I always felt it ran better then after when I fixed it

      +john jensen Mine was not that bad, I just changed the o2 sensor an hr ago, Video on that soon, It runs decent now. If its really running bad, Check for vac leaks, you will hear it, those crappy hoses, nylon tubes will split with age) Pull off the air cleaner, make sure one of the injectors is not dumping fuel, just dripping it into the throttle body instead of spraying. If that's good, Unplug the MAP sensor, (green connector it always breaks) if it runs better the map sensor could be bad That or the o2 sensor could be sleepy. Does it run on when its cold? Gets worse when it warms up? If you have a few OBD1 cars Get a a OBD1 USB cable and find a free program that give you live data, Its a ghetto scan tool but it works.

      Could be if it runs rough or rich then back to normal ONLY in closed loop, (when it warms up about 150* degrees coolant temp) Best is to get some sort of logging tool and check the o2 sensor waves. Now I have a CLONE GM tech 2 scan tool, u can buy one too they are allover ali express or ebay for 250-300 bucks shipped from china Works just like the GM tech 2 and works good on OBD1 vehicles.

      If the O2 sensor was the problem , the ECM (Computer) fuel trim counts should immediately start changing back to around 128 on the long term. I usually just disconnect the battery for a minute because it clears all the computers adjustments it may of made with a bad sensor.

      actually they are close to center in the vid. 128 is the center point iirc 108 isnt too far. I bet while driving it gets out of whack. But idlying like this, the o2 only looks lazy in cross counts, so it may stick at one point when driving, and throw the trims way out of wack and backing it the fuel, causing the drivability problems
