Hi all--
Just thought I'd share a bit of knowledge with you that I recently learned. My 85 Deville (34,000 miles) has been battling a hesitation problem for some time now, but I just discovered the issue. The car just didn't seem to have much pull once I hit the gas (it would hesitate, then gradually build power), and if I mashed it, I sometimes got a backfire (didn't do that again once it did it the first time).
Well, believe it or not, my problem was a plugged-solid crankcase breather filter in the air cleaner. I had replaced the PCV when I bought the car, but never touched the breather pad in the air cleaner. Then, when I was messing around the other day, I noticed it was VERY dirty, and I wondered how any air could pass through it--then it hit me. I disconnected it from the vent hose and drove the car around the block. The hesitation was gone!
I've driven it for 500 more miles, and it appears to be cured. Just a tip to you all, this element is supposed to be replaced every 30,000 miles, so for $5, you should probably invest in one, and maybe it'll help!
