Ok....After pushing my car a little bit last night...it will not idle now.

Upon inspection, I noticed that my knock sensor wire harness came off the actual knock sensor (wtf)

I pulled the spark plugs, and noticed that the 4th cylinder plug had the prong chipped or melted off...I replaced the spark plug and knock sensor ****...and started the car and it still ran like it was previously.

I took off the spark plug wire for the 4th cylinder, started the car and it was no different that if it had all four wires. I didnt get a chance to do a compression test...I had to catch a bus back to school.

Any suggestions? Would a compression test tell me anything other than the fact Im losing compression? In other words...would it tell me anything important before I start to take the motor apart...

Thanks in advance

If a spark plug wire was defective...or fucked up distributor, would i still hold vacuum even though the cylinder was not getting any spark?

Could this be a simple ignition problem?

sounds like cylinder number four is dead by the sounds of it.

yeh I thought so too...bent a valve or cracked a piston ring...i dunno...Im not at my car, I wish I was though...

if it was a bent valve or soemthin like that wouldnt it still get spark from the distributor tho? which i dont think it was

sounds like BAD detonation.

the detonation may have caused something to happen...but its not detonating at idle

I would say that the number four piston are gone.

spark plug prong melted = sever detonation

any ideas as to why it was detonating then?
