Appreciate the kind words, thanks Will. I find the same thing, that tinkering has been a good way to keep distracted from other things; have definitely been occupied with troubleshooting the lean condition - I think I've pulled the battery in and out about a dozen times going after various sensors, etc.. lol. We've also kept busy doing family activities together, which has been good.
Summer too short? It's already starting in May and will stay hot until September! Am looking forward to having it run reliably. My 1981 Toyota truck with a 1987 22RE swapped in took a fresh battery, didn't start, I kicked the F* out of the starter, and she runs - always runs for me.. FJC is the same way. Just don't have the trust with the Yaris yet. Apparently the rule of not messing with the daily driver was supposed to apply to cars as it did with my trucks, so my wife says now.. Never-the-less, did make progress - dumped the fuel tank to a jerry can, as much as would siphon out, and added a dozen liters of fresh fuel. The misfires have cleared now, but still lean. Running through fuel, air, spark as usual... Can't imagine fuel is still a problem. Fuel is fresh(er), and being delivered; other 2ZR swaps haven't upgraded the fuel pump, so I don't imagine I'm starving the injectors; could be weak power to injectors if it was wiring.. maybe? Or maybe still just poor quality fuel. Air: there's too much of it, lol. I've clamped up the exhaust leak good and tight now (no smell, fumes, 'smoke' etc.. detectable), and chased all the lines downstream of the MAF for in leakage - can't find anything. MAF checks out resistance measurement wise, but still wondering if the Cold Air Intake is causing issue due to differing diameters - the diameter narrows at the MAF in order to avoid the issue, but again, maybe the FAE is more picky? Throttle body makes some weird noises, but seems to operate open and closed when in the ON position. Spark: doesn't seem to be an issue, as it runs, but then maybe a weak spark if the wiring is causing an issue? Haven't put too much weight on the spark, but open to suggestions. Waiting on a Techstream compatible cable to arrive from an online order. Once I have it and get it setup I'll get a 2-day subscription over a weekend and run through the workshop manual troubleshooting that requires Techstream - it will be able to run sensor and component tests beyond resistance and voltage measurements that I can do currently. So far, I'm boggled. I DID, however, get my Mishimoto Fan Controller installed and wired up - was actually fairly straight forward, and I actually used some jumpers in the main Junction Box to keep the factory fan connector in place; once again, if I have to pull the whole sh-bang, there's no modification to the factory Yaris harness. -- Adam |
