I just started having some major problems with my 02 Civic Ex ,115k miles, Manual Tranny

On my way to the wash this morning i was stopingfor a red light and as i put in the clutch and pressed the brakes instead of going to idle thetach just dropped to 0 and the car died. It just stopped idling.I tried starting it but couldn't without holding the gas down.It startedshaking and rattlingfrom thedriver side engine bay itgot worse and worsethen when i got on the highway to get home i could barely get the car up to 55. I had to try and get home without letting off the gas or the car would die. The shaking and loud noises out of the engine bay follow the revs. I am new to the Civic and would appreciate any help. Thanks

 

TPS sensor maybe? Got a Multimeter?

 

Could be MAP, or IACV.

 

Multimeter?

 

 

ya i do,i just went back out and it starts without gas and idles now but the knocking is still there and loud, also the big bolt that holds the alternator on is rattling itself loose could that be a part of it. Thanks again

 

The knocking sounds like its coming from 1 of the cylinders im not sure. What could cause both these problems at the same time? What could cause it not to idle then go back to working fine?
