    Hesitation "Stumble" at various throttle positions

    Update. Headed out to Wicked Garage to run a test on the MAF. The objective was to monitor the MAF graph while tapping the MAF with the head of a screwdriver. Each tap resulted in a spike in the MAF and IPW. Spikes ranged from 13-24. There are 5 files attached. 014 is the MAFtap. 015-018 are...

    Hesitation "Stumble" at various throttle positions

    Found a known good original MAF and ECM (thanks to Dank GN and Turbo Keith). Actually, I'll have two MAFs and one ECM. Expect parts to be shipped soon. I'm in Canada so the parts might take a while. Will post an update once we get the parts and install. We're also getting the Denso O2 so we...

    KNOWN GOOD MAF & ECM

    Hi everyone. Trying to rid some demons in my GN. I'm at a point where I need to be swapping out parts with KNOWN good parts. I'm starting with the MAF and ECM. I'm looking for originals. Thanks in advance for your support!

    Hesitation "Stumble" at various throttle positions

    Thanks for the direction. Agree to start with the 02 sensor. I think the tricky part is the MAF and ECM and finding a KNOWN good. I'll post up on the parts wanted forum. i'm meeting with my mechanic tomorrow to talk about this and my previous post. will provide an update afterwards.

    Hesitation "Stumble" at various throttle positions

    See attached spreadsheet for my worksheet. The ACTIONS tab lists out my next steps. This list is based on multiple sources of research on turbobuick.com, vortexbuicks-etc.com, buickturboregal.com. I in no way created this by myself and wouldn't dare take any credit for it. I tried to tailor...

    Hesitation "Stumble" at various throttle positions

    Hey Scooby Doo. Another quick question. Do you know how I can find out if the original KB chip is open or closed loop? Reason I ask is most of the time O2 at idle is around .800mv. When i was responding to your question about O2 sluggishness, I perceived the O2 pegged at .800 as sluggish...

    Hesitation "Stumble" at various throttle positions

    Hi Scooby Doo, the mechanic said that he unplugged the MAF and we still had the same problems. Are you seeing something in the MAF readings? I do see a lot of spikes that seem to correlate with LV8, IPW and IDC. Thanks again for taking a look at the files.

    Hesitation "Stumble" at various throttle positions

    Hey Scooby Doo. Thanks for taking a boo at the files. In terms of CC's, if one were to base an assessment on the following source, http://www.vortexbuicks-etc.com/basics.htm, where "a good sensor will increment counts at least 8-12 (as a minimum) per ScanMaster frame. That would be about 30...

    Hesitation "Stumble" at various throttle positions

    TPS Sweep: Scooby Doo, all looked good from what we could tell. There is a .dat file attached “004_2016.08.12_DARKRYD_HESITATE_TPSsweep.dat” Cam Sensor: TurboBuRick, we started the engine, removed the Cam Sensor and we still had the same problem. Unfortunately, we didn’t get a Powerlogger...
