    Rhythmic RPM Jumping

    I actually still have the same intake that the car came with, it's just a generic no-brand 4" Pipe. I only replaced the filter during the tear down with a generic Amazon brand. The RPMs would still climb when put into gear when I first bought it (they'd stay around 1250 or so), but it wouldnt...

    Rhythmic RPM Jumping

    I see, OK so one step at a time. I should be home in about 2 hours but just wanted to make sure I'm understanding right. When you say you'd like to see an unmolested base map, are you asking me to just reflash the same base map I have on there now and log it the same way with the same...

    Rhythmic RPM Jumping

    Damn, that's about the last kind of reply I wanted lol so I basically bought someone else's headache. I'll try uploading the same Base Map file they sent me and report the results back here by tonight. If it still behaves the same way, what else might you be thinking I could do or test? (Also PM...

    Rhythmic RPM Jumping

    Thanks for the list, I saved a preset for it. One more log with those parameters attached, the recording started immediately after a cold start (bypassed). It's only showing a P2010 (Intake Manifold Runner Control Circuit High) and a P2004 (Intake Manifold Runner Control Stuck Open) which I am...

    Rhythmic RPM Jumping

    Managed to pull this log tonight. The logs are split because I popped a CEL P2010 (Intake Manifold Runner Control Circuit High) and reading the code interrupted the recording. First log is cold start bypass and 2nd log is some operating temp revs, and gear shifts while holding clutch, note the...

    Rhythmic RPM Jumping

    Update! I spliced in a brand new MAP pigtail last Friday. Have started the car and let it idle to get to operating temps. No CEL and idling seemed smooth around 1K RPM. As soon as I put it into any gear, the RPMs rise to about 1500 and stay there - unlike before where they would flutter. This...

    Rhythmic RPM Jumping

    Vac leak is possible, I had a couple small ones before. I found them using a smoke machine from Amazon. It creates the smoke using baby oil. The smoke actually left a light coat of baby oil along the inside of the intake piping. That's why I had the idea to clean the MAP, maybe it got a light...

    Rhythmic RPM Jumping

    Thanks for your help. The MAP Sensor should be included with the Base Map I received as Damond asked for the Part # of the one I have, but I'm just assuming. I'll confirm with them today. If it is tuned for, is it safe to clean it with some CRC Electric parts cleaner? Sent from my SM-N986U...

    Rhythmic RPM Jumping

    New update, got it all plugged up and put back together again, hopefully with all the correct plugs connected. Started up after leaving battery disconnected so all codes are definitely wiped. No code at all during startup. Let it warm up a bit to keep an eye on things and after ECT was above...

    Rhythmic RPM Jumping

    New update: Checked wiring diagram (Thank you Metal Members section!) for Knock Sensor routing and come to realize that the Orange/Blue & Black/White wire I've been tracing actually belongs to the "Variable Swirl Shutter Valve Switch" ... the Knock Sensor has the same exact connector with a...

    Good point - original post updated, thanks. Sorry for the novel, I tend to do that. Sent from my SM-N986U using Tapatalk

    Rhythmic RPM Jumping

    Makes sense, thanks for the direction. So since codes likely unrelated, I'll keep searching for this invisible short and plug up the catch can before buttoning everything up again. Do you have any special tips looking for shorts? I tried continuity already (which there was) and a visual...

    Rhythmic RPM Jumping

    Thanks for the advice - so right now, I basically have the entire intake/battery area connections disconnected with all the wiring exposed. You think this is more of a vacuum-leak type of issue? Should I just connect everything back up and plug up the catch can and try driving it? I tried...

    Rhythmic RPM Jumping

    Update 3: Bought a Power Probe 3 and ECT3000 to try and locate a break in the wires and keep getting inconsistent readings. Wasted 2 days just trying to trace the 2 knock sensor wires. I decided to give that up for now and try doing a continuity test from one end of the wire to the other. The...

    Rhythmic RPM Jumping

    Update: MAF spray didn't seem to reveal any leaks and the MAP sensor was connected properly. Third start-up and it still jumps between 1-2k. Not sure what else can be done now. 2nd Update: Rather than make a new post, I had the idea that maybe the way my vacuum lines are run is a problem. I've...

    Year/Make/Model: 2007 Mazdaspeed6 Mileage: 80K on Engine / 144K on Odometer Location: NYC (Sea level) Concern: RPMs flutter rhythmically between 1K-2K once put in any gear with foot still on clutch DTC's: P0108 (Manifold Absolute Pressure/Barometric Pressure Circuit High Input), P0327 (Knock...

    Possible Throttle Issue

    Late reply, but could help a future search. The fix was either the new Damond base map tune or one of the IM runner vac leaks (really think it was this). I also swapped trans fluid and replaced pivot shaft seal, but I don't think that was the fix, either. Idle RPM at operating temp sits around...

    Scarlet's Story

    Front end is on and everything fired up, first try. Planning to go for the first drive today and log the base map, finally. @Easter Bunny was right, that Greg Sange VTCS relay didn't help, so I'll have to source the connector and make a new pigtail to hook up the black box I got from the...
