My truck idles great but when you give it a little gas the motor jumps around and wobbles. Even the tension pulley for the belts jumps up and down. Rats have chewed into what I am guessing to be my oxygen lines which are hooked to a box which is hooked to my coil box and wire.I replaced the lines but it didn't help

Id check all of the vaccum lines for leaks. You can put them in soapy water and blow on one end and see if it bubbles plug the other end.

Also since mice/rats/squirrels were in there check the wiring also. Just a knick and the wires shorting out will affect you. Let me know when you post back. Check all of the wires. Disconnect them and check they might be damaged where you cant see.

Ah ok now I see from the bottom of that box the lines are hooked to, there are some red wires that have been chewed into. Its pretty much still intact but there are a few wires sticking up from it that arent sendin all the fire it may need. AND one other thing. Up under that aluminum thing that the air intake runs into where the 5.8 efi is printed on there is a plug that comes out the top of the block and the wires on top of that plug are completely gone not sure if this is the crank shaft sensor or what but ill get all these wires replaced and see what happens next. Thanks for your time and concern. JOSH.

That could be the intake air temp sensor.

Glad to hear you gave it a second look. This should fix your problem. If possible solder in the new wire that way you dont get bad readings. If you cant I suggest new wiring harnesses or just simply twisiting them together and taping isnt feasable.
