3.8 6cyl.
Had this problem recently. To the point car stalled on road. Restarted and off I went. Said replace gas cap. Computer said change MAF sensor. That was done. Error code went away. Car does not stall, but has a rough or intermittent hesitation. Mechanic said change coil packs. Changed all. No difference, I am out another $100.00 . OK, still hesitates. Mechanic says change harmonic balancer? Sounds expensive. Only fuel used has been Chevron. Filters are all new. In order of least expensive parts to most expensive procedure what do we do next? No error codes are indicated.
Thanks

I know on my wifes Buick we cleaned the MAF sensor and got a new idle air control valve it ran great for a while, then started playing up again so I bought a new MAF sensor and all was good. Now later on it was messing up, I cant remember if it was the same stalling or just a misfire but I bought a new ignition control module and it ran perfect. Both of these parts I got from advanceautoparts, I did a search for coupons and bought online but picked up in store, I saved $40 off $110, do a search for coupons and save loads, good luck.
I also have the same problem. Changed the fuel pump couple years ago, changed filters couple months ago and the fuel pressure switch. Get the kicking usually about 15 0r 20 miles down the road and sometimes with in the first couple. Car has 263,000 miles on it but runs great normally. Am now lost
