last thursday my truck just died going down the interstate. it acted like it was out of gas. we have changed the rotor, coil, distributor, spark plugs, wires and fuel filter. the spark plugs are not the double platlinum, the are just the regular ones. after all that, we drive down the road as long as you are giving it gas you are fine, you let it cruise and it jumps and sputs. we tried to fix the time but it has a locked distributor that will not let you adjust the time. please help.

i have this problem resolved. we had to put a brand new distributor in it. now it is showing a p0420 code. but i have had my cataylt converter checked and it is good. some times it will act like it is losing power and when you make a right hand turn it makes a awful noise and you give it gas and it does not want to go. please help me.

If you messed with the distributer then you must take the truck to the a dealer to have the timing set. A special scan tool is used to adjust or set the timing, and a dealer is usually the only place that will have this scan tool.
The only ignition parts that will work properly in this Tahoe is A/C Delco brand. If you installed anyother brand then change those parts.
What is the fuel pressure?

A p0420 code could be the result of the timing being off just a little (among other things). Being that you say that your cat. converter is good, have the timing set properly at a dealer. Have the computer reflashed while you are at it...If the code comes returns, check back.
