I had a new timing belt installed on my 03 prerunner 3.4l. Been back on the road for almost 2 weeks and today it all the sudden has sporadic jerking and missing feel. Would it take 2 weeks for this to be caused from timing belt or should I look elsewhere?
Would an incorrect install of timing belt misfire happen right away or not? on 2003 Toyota Tacoma

Most likely ignition misfire and not belt related.
U R welcom. A scan test will reveal the problem cylinder(s) and the cause.

You might try this. If engine runs rough all the time, while it is idling, disconnect one spark plug at a time. If engine runs the same with that plug disconnected, and does not get worse, you probably have a bad plug, bad wire, bad individual coil, or bad injector.
