So, my timing belt snapped on me on the highway last Thursday (on my birthday of all days, can you believe it!?) After a new timing belt and water pump, the car fired up but started idling kind off strange, plus my boost gauge was reading around 14-17 mm hg. At first, I got a P0106 but I think it was caused by a vac leak from a broken hose leading to a solenoid mounted behind the passenger side strut tower (I'm guessing its the purge control solenoid) and another leak between the IM and (I'm guessing again) the EGR modulator solenoid. I went ahead and replaced those vac hoses and even installed new coil packs just in case (the old ones were kind of squishy anyway.)
So far, that code hasn't come back but the car still runs like crap at idle and after warm-up doesn't idle at all. The funny thing is, when I drove it around the block or when I just revved the car, it ran nice and smooth, even the boost gauge started reading around 20-21 mm hg. Its just at idle, it runs like piss and is at 14-17 mm hg. Also, when I slow down, my wide band is at around 20.5, indicating its running really lean and when its idling, its either around 10.5 or 20.5.
Any ideas on what's causing this? I'm assuming this isn't due to bent valves since (assuming it idled at all) it would run like crap no matter what the engine speed was. Could it be IAC, EGR stuck open maybe? If the cams were off by one tooth with respect to the crank, would that cause this issue? The spark plugs looked like they may need replacing too, could that be the issue?
Thanks in advance!
