Looks like my idle engine is dying. The idle is very rough (more and more) and idling rpm is not equal. And today, when I started the car, the idle was rough and the rpm was at 0 (but engine was still running)

Trouble with RPM sensor or idle?

Someone?

Sounds like an ignition problem. If the engine is running, you're obviously getting spark, but the tach reading 0 means it's not seeing the spark signal so obviously something is wrong there.

I'm not sure if I can trust my rpm. Sometime, when I drive, the rpm will be 3-400 more than what it should be. Example at 70 in third gear, rpm should be at 3000rpm. Yesterday, it was at 3100rpm at 60. (With a brand new clutch, it shouldn't be slipping)

But when driving, the engine is running normal. Same power, same fuel economy, nothing unusual on this side.

start ignoring your tachometer.

check tylers "no start" thread. Sounds like it could be a faulty crank sensor if it's not a spark problem.

Raz, it's not just the tach. At idle, the engine is running, but it's running "square". It's only a idle problem. That's why I was wondering about the idle engine.
