I'm new to the site, so bear with me. I have a automatic 2006 Dodge Ram 1500 4.7 4x4. (139k) All of a sudden the other day, driving about 40ish, my truck began to jerk hard while accelerating. Luckily it threw a code for the crank sensor. Picked up a new crank and cam sensor and put them in that day. CEL went away, but still the jerking. I've been reading up on DIY for it, a lot of people say plugs and wires. I'm changing those this week. But i just wanted to know if anyone else has been having this issue and if it was plugs and wires and nothing too serious. Just needing to know if I should pick up the distributor too. Thanks for the help.

 

Erm, the 4.7 doesn't have a distributor cap I though..... Not sure if it has plug wires either.... (coil near plug) although, there are rumors that the coils fire the plug they are sitting on, and another one elsewhere...... if you have two plugs per cylinder.... don't know if the 4.7 did that particular trick.

Also, if you just went to the parts store to buy the cam and crank sensors, they may STILL be causing you issues..... these trucks simply do NOT like aftermarket sensors.......

 

You're right, just the ignition coils. I just got the truck last week, so haven't been under the hood much to tell. Guess we'll figure that out tomorrow. Thanks for the heads up.

 

Just an FYI, changed the plugs, cleaned the O2 sensor and throttle body and everything runs like it should again.
