Engine will not idle?

Put on a new ignition module. Thanks again for the help. It starts now but it runs rough and sometimes back fires. Test drive and it run so bad it would hardly go. I get code 22 for the tps but I had put a new one on already. I just took it off and used the old round bushing and put new one on. Did I need to do something else?

I do not find any bad vacuum hoses or leeks gasket seems to be ok also.

With your help and expert advice we have old truck going down the road smooth. Makes me fell good. Thank You very much. Hope my small donation helps.

I have a 94 chevy 1500 w/t, with a 6 cyl 4.3 liter engine. It is also a 5 speed transmission. The problem that im having with my truck is that somtimes when it is warmed up or warm outside the truck trys to stall at stop lights. I have had it tuned up, filters all replaced. I have spent over $1000 trying to get this fixed and all I keep hearing is "it ran fine when we had it". Please help me.

I didn't find any vacuum leaks. But the EGR was very dirty. So I have it siitting in carb cleaner. I Also found that I have a leak in the exhust around the Y pipe.
