ive been on the forum befor asking Q's about idle and stalling and tried all the responses from you guys.I found the problem on why my 88 vert was acting rough and idle not steady and white smoke coming out the exhaust.my power steering hose was squirting into the relays that allow air to what ever there task are where not getting the air it needed.After the pain in the rear install of the hose and putting on the rack an pinion it ran perfect.
