Just wondering if this sounds familiar to anyone else on here.
I have been having a problem with my idle on startup for about a year now that I track on and off when I have time. It is on the truck with the mods in my sig.
This has happened ever since the new shortblock and heads. The truck will start up fine and then start to miss randomly about 5 or 10 seconds after startup. It sounds like the number of cylinders missing varies. It will do this for a minute or two, and eventually calm down. It does this hot or cold on startup, but only if the truck has sat for at least 20 minutes or so.
I found a very slight draindown in the reservoir that I fixed, changed to different injectors (Bcodes
), swapped cps
a couple of times, changed the oil, checked for fuel pressure and it is constant, Joey has gone through the hpops just to be sure. I think that is most of what I have done.
I hope to get Auto Enginuity on it soon, and do a compression check, but the motor runs and idles great once it has fun for a few minutes, so I am just not sure.
Any Ideas or past problems that you had that had similar symptoms? I am a pretty patient guy but this one is really starting to get to me.
Thanks in advance.
