Ah yeah, even if you find something wrong, they're gonna want approval before you tear into it.
You said you looked at the air filter? Seemed in decent shape? I've seen it where the filter doesn't provide laminar flow over the MAF, and ends up skewing the trims AND VE calculations. Removing the filter doesn't help.
Swing and a miss. :lol: I really don't like how the O2's still go lean at WOT. If it was just a VE issue (cat, intake), they'd be high. It screams air measurement issue, but there really doesn't seem to be one.
I think we are getting on the right track removed intake manifold again found a rag shoved in an intake runner. Plus he repaired the intake runner control wrong the intake runners were open at idle but closing at higher rpms. Had the rods reversed. So the pcm seen movement of the system but it was total backwards. Remind you I wasn’t there when I told him to pull the intake originally he said he moved the wiring harness because the rods originally different move as they were jammed
No wonder this thing couldn't breathe right. :silly: So how's the VE numbers after getting the intake straightened out? Did the O2's start behaving correctly?
