visually everything is great, I will smoke test it tomorrow, just to be sure
That's actually a pretty good idea, my vacuum is lower than it should be, I will check the hose behind the intake manifold and see if I forgot to reattach it, as soon as it cools down
I upgraded my snake eater injectors to snake eater pro injectors, however now my idle hangs around 1300-1400 when coasting and 1000-1100 at idle. If i let off the gas my car will drive itself.
I...
Thank you very much, I will double check, I had a mechanical gauge on the rail recently and it read 58 after being primed, but I've never watched it while cranking. I appreciate the help
2007 C6 Z06 Twin Turbo, big cam. the high torque aftermarket starter, and battery have no issues, they can crank the car without problems when its hot, there's no slow crank or anything like that. If...
Thank you both so much, I did recently add many pids when I was hunting some issues, I do have it connected to the laptop, so if it looks so slow that it seems the laptop isn't even connected, I...
First thank you to everyone, my 2007 c6 z06 big cam, twin turbo, methanol breathing monstrosity runs, and I drive it daily thanks to all the help from this forum.
I have been working on getting...
I am not an expert but will do my best to offer some advice from personal experience. I am sure you have noticed your Cylinder airmass, map, spark, and rpm all fluctuate like a roller coaster. Your...
I was hoping to hear that. Thank you, it's not quite that easy a question to answer by searching online, I greatly appreciate the reassurance and recommendation.
i followed the ls rocker arm torque procedure, once you have set everything to zero lash, you should only be able to crank the torque wrench so far before getting to 22lbs, if too far than you need a...
I get 2 misfires when cranking pretty consistently, but not in the same cylinders. Cranking doesn't seem to be affected, and I am wondering if this is just from the mods, or if this is causing damage...
I am pleased to hear you got it fixed by removing air from the base running airflow, I would recommend you check out your idle settings too. Your minimum idle settings are actually above your base...
Apologies for such a delay, sometimes work does not allow me the time to work on the car. Everything is fixed now, thank you to everyone for their input and contribution.
Rocker arms had loosened,...
You think bad plugs are causing half my cylinders on each side not to fire? The plugs are brand new, and the half that is not firing look brand new, like they are not getting gas either. It's as if...
OK so not all my cylinders are firing. I pulled the plugs and only half are firing. But i get no codes other than failed maf that i intended to get.
Is this a sign of a bad ecm?
That's exactly what I was wondering, if the ecm crapped out after 100 or so flashes. And sorry for not answering the prior question, the vacuum is correct at idle, it bounces around with rpm, when...
Would a blown head gasket cause higher map and lower vacuum?
OK map sensor is correct, vacuum is half what it should be. I did the leak test and there was a leak, replaced intake manifold, it runs better, but map never went under 75 kpa and it should be under...
Daaaaaamn lol that's a really good idea. I do have pressure pumps and vacuum pumps. Idk why I never thought of testing the sensor directly, lol. Thank you I will try that too.
I absolutely do and will verify before pulling the heads again. It's all good it only takes a few hours to pop em off. Thank you all again for giving me more to consider than just a leak....
Thank you very much for the advice and info, I was not sure what mechanical problems cause high map, I thought it could be an air leak in the intake manifold causing it to lose vacuum and breathe...
Yes, I will check it with a physical gauge if the smoke leak test does not show any leaks.
Great questions, this is where I'm stuck according to hp tuners I have matching kpa at key off around 98 or 99kpa, same as what atmospheric shows.
When it's idling vacuum shows around 15kpa and...
Thank you all for the replies, the car ran great already with these settings, when the map is where its supposed to be, then it references the correct cells. With map being in the upper 80s and 90s...
