have a 91 corsica with 3.1. it sometimes cuts out and then dies when going up hills. also if it sits in hot sun for a long time it takes forever to start. just had a check engine light come on. it is code 22 and 24. code 22 is for tps. would that cause car to die intermittently? i have replace all ignition parts of engine besides the tps and egr. fuel pressure is good also. thanks!
