Re: 88 Omni, Running issues, Need some advice.
Sooo... I went to hook up the vac gauge today and one of the hoses crumbled. So I spent today replacing all the vacuum lines I could find (per the diagrams). It's all fresh now. I didn't do the booster line because it seemed fine and it's on there super tight with those fiddly snap rings. I left that alone for now, but did every other line on the vacuum diagram. Finding all the right hose took all day, most the shop were out of the right sizes :) i also cleaned all the accessable electrical connectors.. anyway...
Quick question on that- there is a check valve going from the line with the pcv to the back side if the TB- what direction should it be allowing vacuum? Wasn't sure I got it right.
I stil have my problem though. It is running pretty well in park or neutral, no puffs or miss sounds out of the exhaust, darn near perfect .... But it's really rough and still has the stumble in gear (drive or reverse). It even stalled when I shifted into drive once and at crusing speed it feels, I don't know- choppy? It gets more rough like when you turn the wheel at stand still, or turn on ac or something else that draws power. My rpms drop down to 700 and stay there for a bit, then might bump up, then it stumbles, then back down to 700 or so- no matter if something power draining is operating or not. But in park or neutral turning the wheel and so on doesn't affect it ... I talked to a few people around here that are convinced it isn't a fuel system problem if it only does it in gear.. So I'm stumped. Torque converter problem, sensor to do with the trans? Would an injector, pump or regulator problem only be a obvious in gear?
As for the vents- I played with it a bit, it works for a few if the fan speed is lower, turn it to high and it goes to de frost until you turn it off again for a while. No disconnected lines. I didn't replace this lines yet either, would it help or would it be something else?
