Have you looked at the long term and short term fuel trims at idle and at say 3k revz? Maybe a vacuum leak that seals at it gets hotter? Just a thougt
I also wanted to add, only codes i get are P1519- cam overadvance (I believe where the last owner likely attempted a VANOS seal job aid installed the intakw helical 1 link off, however don’t believe it would be causing my issue here, thanks
As I stated above, overnight, or after several looong hours, shes very hard to crank (spins fine just hard to start), and when she does finally start, horrible loping, what feels like misfires, and absolutely no power whatsoever. Even full pedal, she want get past 2000-2500 rpm and loping the entire tone. If I stop, turn her off and immediately crank her back up, half the time She runs fine, and co to yes to run from the rest of reu day. Sometimes, she’ll run fine for a few seconds, then start loping again almost feeling like limp mode or something. However, even during these times, a few more off and in’s, has she runs perfect, and will
contonue to run fine the rest of the day Until overnight or a very long off period again. At first I thought perhPs a clogged fuel filter, especially after getting erratic fuel psi jumping (almost vibrating) between 43-47, and sire enough, at 114k she had the original filter in- couldn’t even blow through it- after changing, the fuel pressure is good now, but still experiencing the same thing and it almost seems like it’s getting worse, I.e., I’m having to stop aid start her more until she finally levels out aid runs fine. My next though is to pull aid clean the cold-start (ICV) valve and reinstall, any thoughts guys? Any help would be greatly appreciated...
Now that I’ve fully figured out my login procedure, I’ll respond much quicker, thanks again!!!
