Looking for fellow speed owner that may have an extra in tank fuel pump assembly. Possibly in VA or willing to ship of you can part with it. Mine is cracked and leaking.
New 140 bar sensor.. actually found another 1 here in my pile of parts. Lol misfire is gone.. guess we couldn't see the forest for the trees. Bahaha. Lol thanks guys.
Guess ill dig into this and see what info I can find on the ckts.. and where they land in the pcm. I remember I bought a sensor so.e1 kn here gave me the part number but it was only a 90bar sensor and wouldn't read over like 1200psi. I have to order a 140 bar sensor from finjector
He said that a 1 cell dip can't be something mechanical it has to be electrical. Rfi last time it was a plug. I cnt buy plugs every 1000 miles.. and that didn't solve the issue. Lol
i had a hotspot on my old internals and they were recently warrantied. had this issue before and after. idk what else to do. in my mind i feel like it has to be coil packs. lol ive never changed them. and when i stretched the spring a few weeks ago the issue went away. tightened a couple clamps...
they way i took what justin said, the pressure isnt really dipping? or the computer is cutting fuel because of the misfire? idk. does anyone have any experience with this happening with a faulty injector or gummed valves? it idles great. and gets good mpg. runs and drives great under normal...
a friend of mine is a mechanic. he put all the info into a program and it came up with upstream O2 sensor, intake valves need cleaned and or faulty injector. anyone had same issue ? id think it would have messed up stft and or messy idol if it were injector or intake valves.. idles fine and...
everything has been tested or gone through fuel wise. so im stuck thinking either a coil pack breaking down or a boost leak possibly? but it only happens at wot high boost.
from like 1700 to 7 or 800 and it breaks up and backfires. new plugs , new hpfp new autotech internals look good cleaned .. new in tank pump. ive had this intermitenty for like a year. i get it cleared up then a few months later its back.
Single cell dip is back. I can't find any info anywhere that helps. High rpm (above 4500) it misfires. Shows hpfp pressure drops just one cell in the data log. Justin at freaktune says misfire . 2nd set of new plugs gapped to .027. Car runs fine otherwise.. maybe a pin hole in a intercooler...
