  1. EGR delete/pcm tune

    S10 / S15
    What year/model/engine size is your truck? If I recall correctly, the CEL for the EGR error can be turned off in the programming of the EEPROM, but you have to have the ability to erase and write to them. I do have that.
  2. What did you do to your first gen today?

    S10 / S15
    Went to scrap yard yesterday and picked up a 33mm front sway bar and a rear. Had already done the 25mm to 29mm on the front a couple years ago, but since I was getting the rear, went ahead and got the 33mm to see how much stiffer it is. Will do the rear in the next few days.
  3. What did you do to your first gen today?

    S10 / S15
    Installed new carpet this past weekend. Perfect fit.
  4. Your 4.3 TBI Experience

    60v6 Forum (2.8/3.4)
    I used a 4.3 throttle body on my 3.4 swap. I went back to the 2.8 throttle body, but using the 4.3 injectors. The reason for doing it was due to the issues of tuning the PE and AE tables with the 4.3 throttle body. The stock BIN file for the 2.8 has different values than one written using that...
  5. Another stuck sensor on 3.4

    60v6 Forum (2.8/3.4)
    Curious to know, what is the part number and BIN code on the ECM that you are going to use?. The number will be something like 1228062 and the BIN code will be a 4 letter code, for example, "ASSB". I'm running an '88 TBI on my 3.4. Still needs some tuning in RPM/vacuum ranges that I don't hit...
  6. ac/heat blows out defrost/floor. not dash??

    S10 / S15
    Another possibility is that there is a vacuum canister under the hood that has vacuum applied to it. The other hose from the canister goes into the firewall about center of the rear of the engine. This vacuum is what controls the actuators. If that canister is bad, or there is a leak in a...
  7. Engine Cranks, won't turn over

    Electrical / Lighting
    How about the ignition control module?
  8. Installed LED turn signals, Load resistor and Electronic flasher= NO DICE

    S10 / S15
    It probably will, but, you may get an indication that a bulb is out when there isn't. Need to clarify some really bad information in this thread about why the load resistors are installed in "parallel". LED bulbs draw very little current in comparison to filament type bulbs. The typical...
  9. 4.3 TBI ecm

    S10 / S15
    Google search would have revealed ALL kinds of information that you are seeking, but I'll throw you a bone....... Go to scrap yard and look for an ECM from a S10/S15 that has/had a 4.3. It'll most likely be a 1228062 part number. You can also use an ECM from a 4.3 Astro. Those will most...
  10. Can't figure it out

  11. 3.4l TBI modified owners, let's see your data logs

    60v6 Forum (2.8/3.4)
    I learned something new just recently that would greatly benefit him and anyone else that has used the 4.3 throttle body. There are a few parameters in the 2.8L BIN file that concern AFR at specific TPS values and TCC unlock/lock limits.
  12. 3.4l TBI modified owners, let's see your data logs

    60v6 Forum (2.8/3.4)
    I've got more than I can count. I've been waiting for over a year to see Jimmykicker's. Anyone else here actually trying to properly tune their 3.4l TBI conversion?
  13. Stalling when coming to stop

    60v6 Forum (2.8/3.4)
    Code 43 is for the ESC circuit. Check to make sure that you have good grounds around that and that the knock sensor is connected. You could have a bad knock sensor. You did not state anything regarding the ICM, which is under the rotor in the distributor. That could also be intermittent, but...
  14. 3.4l swap

    S10 / S15
    If you are going to go TBI, you are going to be using an electric fuel pump. I've done the swap. Currently tuning the eeprom. If you are serious about tuning and getting the most, you might look at getting a Moates Ostrich 2 emulator. This emulator takes the place of the eeprom and as you are...
  15. auto tranny problems

    S10 / S15
    If you have the slightest amount of mechanical skill, why not buy a core and rebuild it? Stock rebuild kit and converter would put you in it about 3-400.
  16. Possible reasons why 1990 S-10 Blazer stuck in Park??

    S10 / S15
    Similar to as previously stated, but if this is an automatic, while the door is open and engine off, shift through the gears slowly, I.E. P, N, R, D, 2, 1 and listen for the gear shift linkage. You should hear a click from underneath as you shift through each position. If you don't, and you have...
  17. headers for 4wd

    60v6 Forum (2.8/3.4)
    I've got an extra set of the 68872 Edelbrock headers. Bought them for the spare 3.4 block I have that I'll probably never do anything with. I might be tempted to sell them if you are interested. Send me a pm.
  18. 93 2.8 5 spd stalling, and rough idle

    60v6 Forum (2.8/3.4)
    I do not recall if the ignition module causes a code at the moment. What I do remember is that it takes 50 cycles on the ignition on/off to erase the codes as programmed in the BIN file. Try this, clear the codes, drive the truck until it starts running bad and then pull the codes. The...
  19. 93 2.8 5 spd stalling, and rough idle

    60v6 Forum (2.8/3.4)
    Jeeze..... I hate seeing people shotgun shit and then want expert diagnosis over the net without following any instruction from anyone that has taken the time to respond....... Ok, rant over. WTF does this mean? Did you disconnect and replace with new lines, or just simply...
  20. 3.4 timing

    60v6 Forum (2.8/3.4)
    With the vacuum disconnected from the distributor, I'd start with the timing somewhere between 8 to 12 degrees.
