'03 Ranger missing on 3 cyl
Question, my Ranger started missing at certain rpm's but when codes were ran it showed no potential causes. I changed the plugs and wires because they needed it anyway and it made the truck run much better in the good rpm range, but still had the miss and stumbling when starting or under load. I hate to say I didn't have the time to work on it myself and took it to the dealer.
They've had it a week and after their first call to Ford engineering were told to change the MAF. It helped some they said, but still misses. After more trouble shooting and finding nothing the engineers told them to open up the front of the engine and check the physical timing and they said it would take 9 hours labor and $1,200 bucks.
Does that sound reasonable? And if the problem isn't fixed, then what? Suggestions?
