Guys, sorry for the stupid question but this part is not covered in my repair manual, neither clilton nor haynes. Is the knock sensor located on the intake manifold? there is a sensor under some air valve near the fuel regulator that has two wires coming off it. Its not a bosh plug, just two wires. I thought it was the temp sensor, but I am no more sure on that since the book shows that as some place else. My car is totally bogged down under load..terrible so and I heard that the knock sensor can do that, and to be honest..I sparked that sensor pretty bad cuz i popped the wire off on accident while it was running and it shorted to ground. Any one have any idea what that thing is? I will try to make a photo of it and post that. Thanks.Here is the picture...is circled in red. (http://bayimg.com/OACmBaAbi)

no picture, anyhow, the knock sensor is on the turbo model only and it's found on the passanger side of the block behind the oil filter, the n/a I believe had a cold start injector in the area you discribe but it does use a standard busch plug

X2 I don't think there should be anything there...the cold start is further foreward and is another bosch type plug just like the normal injectors
