Ok i have a 97 dodge ram 1500 ext cab 4x4
With the 318 i just changed the plugs wires
Distrubtor cap rotory button coil and did
All re wiring of spark plug wires by dealer specs but when i drive and my over drive is on i hit 50-60 mph it jerks like crazy but if the over drive is off it rids smooth wat could b the problem

 

Did it do this prior to replacing the plugs?

Did you route the wires per the TSB (and detailed write up found here) or according to the factory clips?

 

Nevermind, sorry.

 

So, fixed?

If it's fixed, others who are having a similar problem might find it helpful to know what fixed it.

 

Firing order mixed up?

 

No i did it prior to the plug and wire change but worse the fireing order was messed up

 

Im tjinking it might b my crank sensor

 

Is it fixed now then??

 

No i havent changed it yet cuz i cant remove the old cuz its heat locked and they broke the mounting bracket off of it

 

Broken mounting bracket will pretty much assure you that it won't work right. Only two bolts holding it on though.
