My car has been running great for a while now, but today was the end of that streak. I don't think it's the plugs. They are AC Delco plugs and they are maybe 7000 miles old. Here are the symptoms: the speedo and tach needles both jump around like crazy; at idle the tach jumps up and down about 300 RPM and it used to be solid and dead on; power loss under acceleration; it felt like the engine just cut out and stopped working 3 times then it caught again but was still running rough; feels like there is a HUGE cam in the car and I know it's a peanut; under the hood it smelled funny, almost like a burnt smell; and a click sound coming from near the ignition components by the distributor. The burnt smell immediately made me think "wires". They are very close to the manifold on the driver's side (actually, it's close to the silver colored metal piece that is around the manifold that is used to channel warm air up into the snorkel) but I don't know how to tell if the wires are burnt. They don't look it but then again I'm not sure of what I'm looking for. They look like stock wires also. I changed the rotor about the same time I did the plugs. The cap was in good condition so I didn't change it. I also had the ignition coil tested around the time I changed the plugs and it was good. All help and suggestions will be very much appreciated. Thanks

 

try changing the ignition modulein the dist, that could cause some probs

Well, it's new already, lol, but maybe I'll try my spare. I'm changing my cap and wires in the moring so I hope that works. Thanks

 

the speedo jumping around doesn't make sense.. unless you have a bad groud connection..
