First time on the forum, not knowing what I did but my pick up is having issues now. For start its 1991 w150 5.2l TBI carb. Ok so my pick was smoking when starting up then goes away after running a while. So I figured the valve seal were leaking. So I changed the seals on the driver side while doing the hose I thought was from the AC was in the way. So I took off the pump and hose. Them went on my way doing the seal. Got the passenger side and there was another hose and went the header. Weird took it off too. The other end went towards the rear of the truck and was cut and folded. So changed the seals. Plugged the vacuum hoses and started the truck. Boy does it run rough. Spitting and sputtering. So checking things out I noticed that I had broke vacuum lines where the three solenoids meet and I think I fixed them. Truck is still not liking it. So I don't know were to start. Come to find out it wasn't the a/c pump but a smog pump. Should I try reverse all the cut pipes and put the pump back on. It didn't have belt on to start with?
