overheating could be caused by a stuck thermostat or a clogged radiator not firing on #1 plug could be a fouled plug or bad wire or it may be grounding on the block and your coiil may not have been put in at the right mark

Welcome to Fixya Usually this code points to either carbon buildup or a bad EGR valve. However that doesn't rule out the following:
P0113 - The Intake Air Temperature Sensor converts the air temperature into a voltage that is high when the Intake Air is cold and low as the engine warms up. P0113 indicates a high voltage input from the Intake Air Temperature to the Power Train Control Module.
Common Problems That Trigger the P0113 Code
P0404 - Exhaust Gas Recirculation Circuit Range/Performance. Exhaust Gas Recirculation systems are inherently problematic due to carbon buildup in the intake manifold, etc. This normal buildup can lodge in an EGR valve, holding it open when it should be closed. If this is the case, the engine may idle rough, or not at all. If the valve has failed and is NOT opening, then symptoms would be higher combustion temps and as a result, higher Nox emissions. But the latter symptoms aren't going to be noticeable to a driver.
Possible Solutions
1. Using a scan tool command the EGR valve to open while watching the actual EGR position (it will probably be labeled "desired EGR" or something similar). The actual EGR position should be very close to the "desired" EGR position. If it is, then the problem is likely intermittent. It may have been a lodged piece of carbon that has since dislodged, or it could be a bad EGR valve winding that intermittently opens or shorts as the valve temperature changes.
2. If the EGR "desired" position is not close to the "actual" position, then unplug the EGR sensor. Check for a good 5 Volt reference voltage to the connector. If it doesn't show a reference voltage, repair an open or short in the 5 Volt reference circuit.
3. If there is a 5 volt reference voltage, activate the EGR with the scanner, monitor the EGR ground circuit with a DVOM (Digital Volt/Ohm meter). It should indicate a good ground. If it doesn't then repair the ground circuit.
4. If there is a good ground, then check the control circuit. It should indicate voltage that varies according to the percentage that the EGR is open. As it's open more, the voltage should increase accordingly. If it does, then replace the EGR valve.
5. If the voltage doesn't increase incrementally, then repair open or short in EGR control circuit.
P1351 - Ignition Diagnostic Monitor Input Circuit. This is usually a wiring issue at the connector at the distributor, specifically a damaged wire or bad connector. Replace the wires and carefully examine the wires at the distributor if they have 'blind' breaks in the wiring, so feel the insulation and check for areas where it is easy to stretch the wire, indicating a break in the wire.

need to get back to basics, first check engine compression-you say that it's high mileage, so I'd start there-If you have uniform compression across the board, move on to fuel pressure at the top rail-if that is good, with spark it has to run, but make sure your distributor is properly installed (not out 180 degrees).
