I've read several posts on here about suspension, and spark plugs, wires, coils, IACV, etc. I just purchased my Mark 8 two weeks ago, and only drove it three times. Problems are: the car hesitats during driving and a stop, but when I put it in neutral the hesitation stops. Also after about 30 mins, CEL comes on, I've changed the spark plugs already and it made a huge difference, but didn't solve the problem. Now the suspension, only on the passenger side the car is bouncy, squeaky, and loud. The car sits low, I don't think any of the air bags are working. I live in a city with alot of traffic and bumpy roads, what would best in your opinion, do the conversion coil or keep the air ride suspension?
