riverbanks started following 1998 K2500 7.4L Automatic that won't shift into drive or reverse, Missing only when going up a hill, advice on engine mods and and 7 others
Following many forums,it keeps me sharp,on another forum,not to long ago,somewhat similar problem,guy changed the pcm,fixed,he was out of ideas also,the reply from the forum was,"wow,wouldn't have guessed that"
How is this site dying?you have a engine builder/tuner,do you doubt that shop also?lots of people here giving free advise, when they can,a bit of philanthropy,all hidden from the media, bummer,no heroes here
The loses get up and go,could be alternator not charging at low rpm,and at a lower rpm,oil pump is very low flow, just a thought,I would monitor alternator output at idle,holding 13.2v hopefully
You are correct, different,would be the word, not better,my thought was,you submerged the o2's in much,so,nope,what about a fuel pressure test,I see that the fuel pressure regulator was not replaced,how that failed,at the same time as mudding it,who knows, just a guess,as a pressure test would be needed
Nothing hidden that I remember,did you install Icm properly?with the goo?
Take out the spark plugs ,one at a time,look for a very clean one,or crusty gunk on it,this way you can isolate which cylinder is the culprit, the problem could be,intake gasket,head gasket or cracked head
Sounds like a bad power feed wire or fusable link,check those links,the ones leaving the starter, running up the back of motor,do a wire wiggle test,see if it stalls,or with a test light, check for 12v at large red wire at distributor when it's a no start
What is it hooked to?pcv?
Ok,so try the techron cleaner,try a socket on intake manifold bolts, maybe a loose one on #8, another would be to spray a mist of water at #8 injector and manifold,listen for a stumble in the motor,might be a air leak, other than that, injector,big thing with that job is cleaniness,shop vac or compressed air to clean intake,so no debris enters injector holes,not a hard job with new orings
So shift lever won't move?,that's the interlock on the steering column or brake switch
