cel goes out when clutch pedal is pushed, also stalls and dies.

[90rangersuper]

I have a 90 ranger 4.0 supercab 5 speed. Recent new clutch. Truck started running rough and would stall and die when comming to a stop or cornering hard. Doesn't do it all the time. Starts rough now and idle is high at first. When you shift also the rpms don't drop right away. I just put new plugs in hoping it would fix the issue but no. I cleared the codes yesterday and started it up cel came on after about 5 seconds. I got codes 113 intake air temp high or open, 118 engine coolent high or open and 123 tps high or short to power. What is puzzling me is the cel will go off when you push in the clutch and come back on as soon as you engage the clutch. Also pulling codes could only retrieve them with the clutch pedal pushed in, btw the codes are all koer codes. Any help would be great as this is my dd. Thanks in advanve.
