    Misfiring issue

    Yesterday I got a new AC delco cap and rotor and even replaced the distributor drive gear, since it was worn pretty bad. now I get about the same amount of misfires but across more cylinders, not just 6 & 3 I don't know what to do. I'm so tired of diagnosing and spending money... Help? Sent...

    Strange sound

    So today is the first time I used the 4wd in my Yukon, and it made the strangest noise, sounded like the tires were rubbing on the fenders, it worked but the noise bugs me. I was going straight, and the terrain wasn't bumpy just muddy, once I got it on pavement I gave it some gas and it made the...

    Misfiring issue

    I changed out the coil and there was no change, but here's what I'm thinking... My misfires are at cyl 6 and 3, After looking at one of my old caps I see that these two cylinder spark pathways go right next to the main coil input, so maybe that's how my misfires are happening?

    Misfiring issue

    No not at all while driving, only while sitting at a light or in traffic, the idle just goes up and down, and only when it is warmed up real good

    Misfiring issue

    I haven't changed it yet, I will in the morning, I wanted to run my scanner on it today while I drove all day to see where and when my misfires were happening the most. It's definitely only in low rpms (below 1000) and only when cold. On the freeway I get no misfires at all whether hot or...

    Misfiring issue

    Yea I've got the old coil, I just bought a new one just because, it wasn't needed. I'll swap it back out tomorrow. I just put in a new Delphi fuel pump a month ago while it was having this problem and it made no change....

    No they don't need it, they are held up by the metal bar that it's attached to, has a tension clip that holds it up, it's not heavy at all, I'll be drilling some holes to take out some of the weight before I cover it with material

    Yea I don't get it either, for about the first 30 minutes it runs good, no bouncy idle, just nice and smooth then, the idle gets really rough I don't get it at all Sent from my iPhone using Tapatalk

    I hate my visors, as I'm sure most do. So I'm redoing mine. I got this idea because I just got the torque pro app and I decided I needed an out of the way place to house my tablet so here goes... First what I'm dealing with... First steps to get it apart and get it all laid out and marked...

    Misfiring issue

    Ok so I hooked the truck up to my obd2 connector and went through torque pro and I can see my misfires in real time and through history, so after some testing, 99.99999% of my misfires are below 1000rpm either in park at idle (700rpm) or in gear at idle (600-700rpm) at operating temperature...

    Obd2 phone scanners

    I got in my scanner and downloaded torque pro, I haven't gotten to do much with it, i was able to verify it works and put together my dashboard on it, was able to see misfire data both realtime and history which is awesome, now I just need to figure out what other data to watch to know where my...

    Misfiring issue

    Oe everything, I did a smoke test on it to check for vacuum leaks just in case because my idle surges, I already put on a new iac but it doesn't help and the only time it will throw a misfire code is if im stuck in traffic Sent from my iPhone using Tapatalk

    Interesting OBS Yukon You May Or May Not Heard Of

    It's really just a trim package done by Stillen, who made ground effects kits in the 90's. Still nice truck though Sent from my iPhone using Tapatalk

    Misfiring issue

    Decided to pull the cap and rotor and this is what I found seems like something isn't quite right, some of the marks on the cap are higher than the rest and are pitted. the rotor has some arcing on the side of the tip that actually has some of the rotor material actually sticking out from the...

    Obd2 phone scanners

    Wow so much good info for cheap! I guess I'll go through and see if any of the ones mentioned can show misfire history or realtime that will be the most important for me and if it can read codes, those two are important for me Sent from my iPhone using Tapatalk
