It sounds very likely that it is going lean. Could be a bad Mass airflow sensor or a fuel pump, maybe plugged injectors. The first thing to do if you can get your hands on one, is to put a scan tool on it that reads live data and go up a long steady hill while you are watching the O2 sensor voltage. It should toggle back and forth across .5V, if it remains below .5V while you drive, then you know it's not getting enough fuel. If so, check the fuel pressure to spec. If it is good, then the pump is fine and you're chasing the other two.

Sounds like a possible fuel pump problem...When they begin to go bad they will overheat and lock up, then work fine for a while and do the same thing again. By changing the filter you lowered the flow resistance and allowed the pump to work a bit easier but still being bad, it did the same thing again. There are other things that can do this as well, but pump is most common.

Change your fuel filter, it may have gone it's life time and is getting to dirty to let fuel flow properly. Your fuel pump to may be getting weak, if the fuel filter is dirty the pump works harder and heats up and could be over heating the fuel pump relay too. The fuel pump relay i believe is in the glove box behind a panel that say relay, there should be (3) in there and the middle one is the fuel pump's. switch then around after you change the fuel filter and if you get a chance, check your fuel pressure at the shredder valve. Good luck and hope this help's if there is a Auto Zone around you, you can ask to use the fuel pressure gauge to see what fuel pressure you have and they'll have the step by step instructions on how to do it and takes about 5 min to do and will have the fuel filter and step by step to replace that too. Keep me posted, be glad to help.

Missing and backfire.

Backfiring is usually associated with a lean condition. Is fuel pressure correct? Is this vehicle TBI and are both injectors working properly? If timing related it should spark rattle under load and the timing would be way out and not run/start well at idle

Engine cuts out while driving on the highway

JUST SAW, the most common cause of your engine dying and backfiring while driving on highway would be low fuel pressure. check fuel filter for foreign debris. filter may be clogged or restricted, also a weak fuel pujmp. the other thing could also be a stuck e.g.r. valve, this would have some exhaust carbon deposit stuck on the seat of the valve producing a vacuum leak, but it would not idle properly.faulty fuel pump would give you a good engine idle but would starve for fuel at high highway speeds, when the engine needs for fuel for proper operation.

I have problems with my 98 chevy k1500 pickup on the highway. Once i hit about 65 mph it wont accelerate and it backfires. also, after i come to a stop and try to accelerate up to highway speeds again,...

If it is running bad enough to be backfiring, the Check Engine light should be on. I would start with scanning the engine computer for fault codes.

I have a 1993 1500 chevy truck with the 5.7 tbi my problem is the rpms go up and down 200 to 300 points all the time even at highway speeds the truck still seems to run good had the alt. Checked out its...

There are a couple of things i would check for.The first would be a real good check for vacuum leaks all around the intake manifold.2nd i would verify that ignition timing is set where it should be.If these 2 check out ok i would check or replace the idle control motor on the throttle body.Let me know if this helps or you need more info.
