startring off, works fine then going up in rpm it starts to mis fire around 3200-3500 rpm. it feels like the rev limiter hitting early. its a 3.1L. any sugestions...............kc

Well, if your rev-ing the engine in park, it is doing actually what it should.

normaly when rev in park the limiter doesn't hit until 4000rpm. but it is also sputtering while driving at 3200-3500 rpm. seem like fuel or ignition...

Well, it could be a lot of things but since it idles fine that narrows the range a bit.Originally Posted by krcorbett
#1 Change the fuel filter. $10
#2 Check your spark plug wires. Ensure they are all properly seated on the plugs and coils. Look for obvious damage. If they look good so far, time to test them. Look for arc over along the wires while you rev the engine. Checking for arc over is easiest in the dark. Lastly check your wires with a ohm meter, the longest wire should be about 5k ohms and the shortest about 2k ohms. If you need a new set, about $30. Stay away from Bosch, or universal sets.
#3 Replace your spark plugs. Install Autolite 606 spark plugs. $12
If you do all three, your problem should be fixed.
If not, give us an update and we’ll go deeper.

usually plugs or wires......inspect them each individually for what they look like, and replace as necessary.
