it idled pretty damn well with the MAF unplugged. I think the throttle body gasket is to blame, have one on the way. Next on the list is to hook up the wiring going to the cabin. CEL, serial data, coolant temp for the gauge, oil dummy light, alternator light… ---

thanks. anyone have a spare 5-pin maf laying around? I will be pulling codes as soon as I get the OBD2 port hooked up, but I have a feeling the MAF is bad. ---

Idled the car last night looking for cooling and PS leaks. After a few revs, one of the factory BMW cats is glowing red hot. Rich or lean? I’m going to remove those and weld in straight pipes, but I want to solve the condition that’s causing them. It’s possibly a clogged cat, but the car ran pretty well before parking it. Going to pull codes hopefully tomorrow evening and see what the PCM is thinking. ---

You’re probably running very rich or the cat is clogged. Are all cylinders firing? One isn’t missing and dumping a bunch of unburnt fuel? ---

Ironically I actually am all set on parts…I do need a coolant temp pigtail for the temp gauge but I doubt that person is just going to snip it off his harness. Also need a DBC gas pedal (since the one I bought snapped) but I will see if I can grab one out of an E32 or E30 at M&M. > [@LZ](#): > > You’re probably running very rich or the cat is clogged. > > Are all cylinders firing? One isn’t missing and dumping a bunch of unburnt fuel? I am getting a slight misfire every few seconds. I won’t know where until I wire up the OBD2 plug sitting in my toolbox and check it. My buddy dropped one of those OBD to Bluetooth adapters, so I’ll scan it with my phone this weekend. > [@e60oholic](#): > > Gauges work?? Haven’t wired up the coolant temp gauge yet. Tach physically moves with the revs but not on the right scale. The tach reads way too low, I may need to solder in a resistor or something along those lines. Haven’t really looked into it. I finally put the M5 diff with 3.62s back in the car last night. It was one of those nights where every time you crawl under the car, there’s some sort of distraction, the phone rings, etc. Eventually got it in, tightened up, bolted up the back half of the driveshaft, and measured to see how much the front needs to be modified. I’ll be dropping off the shaft today at Fleet Pride. ---

anyone have any spare LS coil packs laying around? individually unplugging coils 1,3,5,7 yielded immediately shittier idle and a misfire. i unplugged 2 and 4 and no change. when i unplugged the ignition connector for all of bank 2, that side dropped out. I’m thinking I may have a few bad coil packs. Picking up a scanner tomorrow to check. ---

well, i think i may have found a new issue/solution… borrowed a scan tool and ghetto rigged an OBD2 plug. i swapped all the coils on the passenger side and kept the MAF plugged in, and it didn’t throw codes for those, so i’m assuming they’re good. however, i did get 2 codes: P0343: Camshaft position sensor high input P0650: MIL Circuit Not worried about the 650 code since I don’t have the CEL control wire hooked up to anything yet. The 0343 code is interesting. This was a known good motor pulled out of a wrecked van, so rather than just throw a new sensor at it, I thought about what I had done to the motor to change it from “stock”. Back when rebuilding it, I installed a used cam out of a 2005 LS2 Vette. Apparently the LS2 uses a cam that provides a position signal on the FRONT of the cam, to a sensor mounted on the front cover. My LQ4 is the same as all LS1s as the cam provides the signal to the sensor in the rear. Therefore, my cam is incompatible with my motor…this could also explain why my tach is not reading correctly. Another symptom is the car not firing on the first try (extended crank period). It will only start if you open the throttle about a quarter.
