I bent the wastegate actuator arm to fit into the S13 space since its an S14 turbo, it all lined up but due to bending the rod i lengthened it a bit. It was opening prematurely at 4psi and after bending it a bit shorter it now builds 8-10PSI before the end of my driveway.
Your manifold gasket leaking or Mani cracked again? It would make your o2 read that lean at idle. Cams wouldn’t have that sort of effect at idle. If anything it would be richer because of cams. What wideband do you have?
Cars that use Mafs to meter air are pretty good even when you hange VE. And widebands only like to read burn fuel.
I think Sheldon is probably right about leaking manifold. Shit injector? Shit maf, shit TPS. So many things.
Car also most likely won’t run if it was actually 18:1. It would lean misfire
3tc would blow your mind.
Actually my 4ag has done it. Youre soo by the books.
Yea the elbow has a very tiny leak which is a piss off cause i dont wanna pull it off again, but i seriously doubt that it was actually idling at 18, even if it was i doubt it would ruin anything.
I’m getting 13.1-13.6 under 9psi at WOT, i dont trust the wideband which is AEM. I mean exhaust leak aside i have no idea how long the sensor has been stuck in the downpipe so close to the turbo as I bought it that way, sensor is probably cooked so I take it with a grain of salt.
Its WAY too stable at all throttle positions at 13.0-12.9. Like half throttle to flooring it it doesnt change, and leans out a touch under boost but again who fucking knows what the actual afr’s look like until I have a sensor in the correct spot and know its not cooked.
It smells pretty rich but i cant give that any credibility. Its getting worse fuel mileage now after flooring it a lot so its obviously consuming fuel more quickly so thats good.
I dunno man. I thought nick told me he had cams. Either way, i guess ill just have to replace the whole goddamn car chasing an issue this blindly.
Oh yea and it was idling at 14-15 just before I got home but wanted to stall at idle a lot. It likes the alledged 18 afr better at idle as far as stability goes.
And sheldon, how would cams make it richer? More duration lets more air in and at idle i thought they used a fuel map not an O2 reading? Shouldnt the same amount of fuel and more air from bigger lift and duration equal a leaner mixture?????????
I dunno. Fuxk.
Andrew Casey had an oil pressure gauge he assumed was wrong. Now he has a new motor. Why would you ignore the only information you have, 13-1 at full load is in the edge of a bad time.
Is fuel pressure correct. What have you replaced on the engine z checked codes?
