put a jumper wire between the bottom two pins in the plug for the throttle position sensor, if it idles down you need to replace the idle throttle position sensor

The valve cover gasket change is related only to the extent of needeing to remove something else . There is the fuel pressure regulator and the MAF SENSOR talks to the ECU telling the computer how much fuel is needed for proper mixture of thre air passing into the intake. It is the first sensor in the intake duct coming out of the sir filter. Make sure all the injectors are secure in wiring connection and look around for any other that had to be removed. All plugs mean it isn't just one injector. Unplug and replug the MAF. cHECK THE THROTTLE POSITIO SENSOT. iT RIGHT THERE where the fuel likage is attached.

Sounds like the switch on the clutch pedal needs adjusted. Is the floor mat bunched up under the pedal, I've seen that. It could also be dirty ground connections. There are several. Not only the battery ground but smaller ones also. A bad ground can mean low voltage to the ECM and injectors. Does the start solenoid click. If it does may be bad battery connections on either end. If it doesn't may be bad connections in the small wires to the solenoid. The alternator could be consuming the available connections when the battery is recharged from starting then the ECM and injectors can have enough. Why it would run rough for a while. The first place to look is always the electrical connections. A lot of people have paid for new starters because of bad connections. I had a friend kept buying alternators from his trusted mechanic because somebody had removed the ground wires from his engine to the chassis. (This was before he asked me to look at it. Of course!)

The 22re timing chain is a double roller and last the lifetime of the car they are bullet proof however the chain tensional is another thing altogether.

Locate the idler pulley. Loosen the nut in the center of the idler pulley. Then loosen the bolt that protrudes from the back of the pulley. This will let the belt go slack.
