November 6, 201312 yr Author No,it is on the other side by the coil.Altitude connector is seperate.You are supposed to disconnect it w/setting timing so that it does not interfere. Compression,vacuum and fuel pressure checks are all good ideas. Miss at hot idle sounds most likely like an unmetered air or vacuum leak, though. I would try injecting some propane into the intake.If the idle smoothes,you can eliminate mechanical problems. Carefully inspect the large rubber intake tube and all associated plumbing for cracks or leaks. PCV hoses too. I had to add a few clamps. good deal. i have a propane torch that'll do the job. i've actually noticed some excess oil seepage around the intake plenum and had recently replaced the PCV valve, i seem to remember the hose being really fragile and/or cracked back in that area. inside diameter on the PCV valve hose should be 3/8" or is it 3/4"?
November 6, 201312 yr Author and as for the miss/rough running, here's the exact sequence: in park and idling while cold - fine in park and idling while warm - okay, but will randomly idle low and die in drive and idling while cold - fine in drive and idling while warm - bad, will idle low and die. when on the throttle (driving) a misfire develops, car runs rough all through the power band (gas is constantly manipulated to keep car running while warm, while in park or in drive) Edited November 6, 201312 yr by lastchance
November 6, 201312 yr good deal. i have a propane torch that'll do the job. i've actually noticed some excess oil seepage around the intake plenum and had recently replaced the PCV valve, i seem to remember the hose being really fragile and/or cracked back in that area. inside diameter on the PCV valve hose should be 3/8" or is it 3/4"? 15mm so 1/2 should work. I`m tempted to try silicone hoses.
November 7, 201312 yr Author got it. i'm going to work on the vacuum hoses and such this weekend, that's an easy/cheap fix to go through and really inspect those bits and pieces.
November 10, 201312 yr Author naru was right... he said vacuum/unmetered leak. the intake boot from the air flow meter to the turbo was not only cracked on the base but the entire middle section was COMPLETELY ripped, almost completely in half. i was worried when i noticed oil at the base of the boot, thinking that something was dying, but nope... just the boot itself completely ripped apart. haha! will the intake boot from an ea82t fit? i assume it's the same part???

There different atleast the ones on the xt-6's are. You could try fixing the one you got with jb weld.
November 10, 201312 yr Author yeah, i have jb weld but would rather dig around the junkyard if one from an ea82t would fit. i could also rig something up with a silicone elbow, reducer, and tubing...
November 11, 201312 yr Auto have you check the vacume modulator on trans is not ruptured the diafram any white smoke ? also have you replaced the diss cap ? have seen many rotors arc to the shaft of diss thru the center of rotor striat down the center look for burns on bottom of rotor. This whould get worse hotter it gets and longer it runs and more load its under. Just a thought
November 11, 201312 yr Author no smoke of any kind, actually. i've replaced the rotor, disty cap, plugs, wires, coil, CTS, and a few other simple/cheap things all within the last 100 miles.
November 12, 201312 yr I had a similar symptom..... multiple issues... Stall, misfire. wont idle wont rev intermittent... all of those symptoms 38 bucks.... New Coil from advance auto. FIXED ALL MY ERATIC BEHAVIOR I replaced... MAF Distributor Computer plugs wires Rotor Cap and Button o2 sensor and a ball joint while I was at it. LOL unhooked the antiknock system in the end the Coil fixed it. good luck

November 21, 201312 yr When checking vehicle electrics look for good mechanical connections as well as good electrical connections, you can for instance pull apart both sides of a multi plug connector and it all tests perfect electrically but when connected find that for instance the female side of the connector does not contact properly with the male pin from the mating connector in a mechanical fashion so the actual electrical connection will then be very poor or worse intermittent.
