98v70t5manual hunting warm start idle for a few min.

Post by 98v70t5mgonegray »

The title pretty much says it, my 98 v70 t5 manual. It started a month or so ago. In florida so its never below 0, and usually pretty warm. Cold start is as it should be, warm start sometimes catches really fast now(like first crank and its off). After it starts it idles normal say, 900rpm then goes down. It catches and recovers before it stalls. It will do this maybe 5 or 6 times then it will go away and will drive and idle perfectly. This is with ac off, and you can feel the bogging even when off idle, like when you are driving off i can feel it bog for the level of acceleration i have it at, then itll catch and feel like a surge.

Within 12 months i have replaced.
