Saturn SL2 does not idle, revs, misses.... Did before I removed

Yes ,the engine is identical, just twin cam instead of a single cam set up.

Possibly bad tpos sensor

Bad idle air control valve

Bad maf sensor

Check the computer codes first before spending any more money on it

Also do a compression check

And check your valve timing and ignition timing just in case.

Check the rubber hose the connects to the cover, it could be dry rotted from the heat and it just made it worse when you removed the cover. It could have cracks in it which you can not see. This is the only thing, unless one of the plug wires were damaged when you removed them.

You should have a dot on the fron of the cam to line up before you put the chain/belt on..

HI, I GOT NISSAN MICRA 1.2 SE 2005 PLATE ONLY DONE 59000 MILES. MISSING! I HAVE CHANGED COIL PACKS, CAMSHAFT SENSOR, TIMMING CHAIN, STILL THE SAME PROBLEM. I HAVE ALREADY SPENT 1000.00 POUNDS. IS THERE ANYONE WITH SAME PROBLEM?

Check your oil first. I guarantee your car burns oil and it may be very low on low. The ticking may be a lifter starved for oil or one that has debris in or on it. The timing chain usually makes a "slapping" sound when it gets slack in it from lack of tensioner adjustment.

A sure fire way to check the timing chain if you are concerned is to take off the valve cover (also a good time to replace the valve cover gasket). Then you can see the chain and feel and see if there is any slack in it.

your pistons are leting blow by get through whick means that your pisten rings are wearing out more then likly

Check with ac on and off ,also check top bolt for alt.

These engines have a timing chain, not a belt. They also have nylon coated guides under the cover that wear. If you change the chain yourself, or have it done, check the guides as well.

Be careful about the PCV valve. If it's the wrong part, it can cause drivability issues. The grommet is important. It seals the valve to the crankcase vapors. Otherwise they leak out nullifing the purpose of the system. Also check on the other side of the valve that the hose back to intake manifold is not clogged or cracked.
