should have posted that I found the correct solution on my own. My reapir manual does'nt indicate that there are adjustments on both cams, so when I startec the engine it was out of time.

bad compressor? (seizing) or
or engine is so weak, at idle (lean), that it cant run your compressor.
the reason for the lope is the ECU idle speed controls going crazy.
id say, the ISC is a victim here.
What you describe is a cylinder not contributing,This can be from a misfire such as a broken sparkplug wire to a broken sparkplug, If it was a vacuum leak it would lope at idle but not buck at high speed,
this is what they call engine loping u need to take it to a mech for proper diagnostic,,, bu check first spark plugs and wires mostly culprit though is timing bad,,,, bad timimg gear/belt/chain which ever is in yours.
1. Vacuum leakage Check throttle body and intake manifold for tightness. check all vacuum hoses.
2. Faulty fuel or pump or electrical.
3. Plugged PVC valve.
4. Air filter clogged
5. Leaking head gasket.
6. Camshaft lobs worn.
All of these porblems can cause lopes or erratic idle.
This car has a very possible chance of having either a slightly bent valve, causing the loping idle, or the belt was installed a tooth off on the timing, it's one of the two.easiest way to deduce this would be to recheck the timing belt marks, to certify they're correct, then to do a simple compression check, get back to me with any questions, I'M HERE TO HELP!!!
1.vacuum leak
2.leaking egr or plugged pcv valve
3.ignition components damp or damaged
4.faulty or incorrectly gapped spark plugs
5.faulty plug wires
6.faulty emmission components
7.air filtr clogged
8.leaking head gasket
9.timing chain or gears worn
first check air filter then check timing with a light make sure its steady if it bounces around the your chain/belt is needing replaced check your wires for frays or just replace them cause their 10 years old
