Got everything put back together. Took 2-3 tries of dying right away before it finally fired up and held. Had a little bit of misfire for a bit...
Awesome. Really appreciate the help here. After we get the vacuum leak figured out we'll start digging into filter options and how we can get...
Well, I'll be. We unplugged the MAF. It died immediately on 1st try. 2nd try, it ran fine. I assume by " a tune that isn't for the intake on...
Thanks for the response. It's an aftermarket intake. Have already pulled the filter. I don't see an airflow straightener. Not even sure what...
2007 Mazdaspeed3 Mileage: ~60k (JDM about 3mo ago) Location: Idaho Concern: My son called and said he couldn't get it to run right. He's up...
Forgot to say, I was able to blow through the pipe towards the engine freely. When I sucked I got just a bit of dirt but it's cleared out now....
Ok. I don't think the engine swap had anything to do with this but... I've been burned once assuming on this project already. Car is running...
Well folks. We have success. I have to preface, I'm an electrical engineer. I know my way around a multimeter. I checked against the negative...
Thanks. Also realized I haven't checked KOEO fuel pressure which should give me pressure without HPFP interaction. If that's at 70psi, then,...
I guess I haven't replaced the Fuel Rail Sensor. That's the only other part I can think of. But - I'm just not seeing how that is the problem.
Ya, just to give the warm fuzzy I resistance checked various spots around the block and HPFP area. All 0's, so no resistive connections. I mean,...
Welp. No joy. It's running better for sure but p0091 still there. Before we weren't even able to make it down the block. This time, we were...
Ya, we swapped that out too. I honestly thought it would be that for sure for exactly the reason you said. I had only done visual check of...
OK folks. Back for more advice. I still have the old engine so we just went brute force with it. We swapped the HPFP (with the spill valve) and...
I'll check koeo when I get back to the car. That was my thought too, it seems like I'm not seeing the hpfp reading OR I am and it's toast. Would...
Hmm. So when I graph it using torque pro, fuel rail pressure as x, it shows 430-500 (a bit bouncy). It doesn't show what the y units are though....
We just swapped in an ms6 engine into our 2007 ms3. It's running but we get an p0091 code. We haven't moved it out of the garage yet, so just...
