I cannot express how distraught i am right now because this shit is boggling my mind. This is gunna be longgg so grab some snacks and get comfy...
Heres my deal, i was on my way up to soysaucecb7s crib (john) to work on tuning the whip, as you saw in our other thread... i had just picked up a few gallons of 93 octane and was about 2 blocks away from the station... I made a right on the main road toward the highway, and as soon as i hit 2nd gear, about 2000rpms the engine literally died and came back to life in a split second, so i thought oh shit maybe i just hit the clutch accidentaly and kept on driving... 3rd gear, 2000rpms, same shit happens and as soon as i put her in 3rd, she started boggin like CRAZZYYY!! soo pig rich my AEM UEGO couldnt even read it and i couldnt even get past 1500 rpms and i barely made it home doin like 20mph in 4th gear lol.... john came over the crib after like 10 min and we got to the troubleshooting. One of the 1st things i checked was all the connections to the ECU and to reload the maps... did absolutely nothing... made sure my cam gear didnt loosen up and throw the timing off... made sure my missing link valve had the filter still in tact, cause it does the same type of thing when thats missing but that was fine... about this time, we realized the vacuum was fucked... she normally idles at around -20in/hg, and she was sitting at about -13-15 in/hg... still crazzy pig rich.... we replaced the injector o rings as we found a small vacuum leak and hoped that was our problem... no luck, same shit, but we did fix that leak so thats 1 plus lol.... we also found yet another fucking oil leak, when i thought i put enough goddamn time and effort and money into fixing oil leaks for the past 2 years... next we checked the timing, which was slightly off somehow, even though timing was dead on up till this point where the motor decided to crap the fuck out on me... readjusted the timing and that got the motor to idle for more than 30 sec before it stalled... we decided to check compression just in case i might have blew a ringland or some shit... that was flawless at anywhere from 190-200psi throughout... found a slight leak in one of the vacuum lines that the boost gauge and wastegate are hooked into, so we decided to unplug and seal up that nipple just to see if that effects it, and that made it worse... it was steady ab around -5-7 in/hg now, and was idling 10x rougher and bareeelyyyyyy staying alive at like 450-600 rpms... we thought, hey maybe, just maybe the map sensor could be fucked... we snatched the black box outa one of my other cbs and hooked that up and hooked up all the vacuum lines and still... the same... fucking... thing... uel pressure is great, oil pressure is great, oil pressure into the turbo is great... still technically runing on the same fuel that i been running the entire past week cause i had about 1/8 tank left before i filled up so its deff. not the fuel... we even unplugged my nology wires and put in my old ngk blues JUST IN CASE, and no difference at ALLLL!!!!
i GUES its posssiibblleeee that the ECU could be defective, but how would that be effecting the vacuum at idle? i'lv NEVER seen anything wrong with my car before effecting the vacuum at idle, i'lv only seen the idle get really rough and such... and alll the tweaking and tuning and reloading of the map we did, it did NOT effect the car at ALLLL... its almost as if my ostrich just crapped out on me or some shit... i checked and replaced the 3 aaa batteries even, in case that was an issue and NOTHING.... tried to plug in an older ECU i "attempted" to chip myself and that had the same effect... I emailed Craig at Moates.net cause it deffinitely seems possible to me that the Ostrich couldve somehow crapped out and just lost the data and maps i had loaded, so it basically brought it back to its factory setting...
If you guys have ANY ideas at ALLLL as to what it could be, let me know. My head hurts sooo bad right now from trying different things over and over again with NO progress other than backwards progress... any help is mucchh appreciated guys, thanks.
