Fixed it...I left igniter unplugged (doh!).....but now rough idle and stalling @ low rpm.

Yep, you were right lenore...igniter was unplugged...but now rough idle and stalling @ low rpms. thanks bro!

Thanks for the input. I decided to give it a try....it was ONLY 100 degrees in Dallas today and it took me about 8 hours. It was a tedious job, though everything seemingly came together at the end...HOWEVER, when I went to start the car, expecting success, it wouldn't start! It cranks, sounds like it wants to start for a couple seconds, then just keeps cranking. I scanned for codes and got a P1300 (Igniter Circuit Malfunction (Bank 1 Or No. 1)). YIKES! I may have more trouble now than before I tackled the knock sensors. At least I could drive it before, but now I'm without wheels. Any ideas? Thank you!

Car won't start. Changed knock sensors today in 100 degree heat (fun!). Looks like I screwed something up cuz now it won't start...turns over, sounds like it wants to start for a couple seconds, then just keeps cranking. Scan gives me P1300. I know I spilled some water/coolant when I refilled. The fill cap sits right on top of the igniter (coil?...i dunno) on bank 1, so maybe it got wet and is now malfunctioning??? Any ideas/suggestions? Thanks!

My 97 ES 300 is throwing knock sensor codes 0325 and 0330 with CEL. From the posts I've read on CL, this may be caused by faulty wiring harness exposed to heat over time. So rather than tackle a big job to replace sensors, or paying big bucks to dealer, I figured I'd try to replace the harness ($27 from Lexus dealer). So, I bought part # 82219-07010 but can't seem to figure out where it goes. Lexus gave me a diagram but I can't find corresponding wire. What am I missing? Do I have to take off the manifold to get to it? (ugh!) Thanks for any help!
