I need major help quick. I need my suburban for a 750 mile trip in 2 days and it isn't running right. I had problems with the engine losing two cylinders on the drivers side they just quit then would start back up in less than a minute. I changed the cap rotor spark plugs and wires and I even went as far as the coil pickup on the distributor. It ran fine for a day after that but now is back to losing power randomly. I'll be giving it gas and the Rome drop instead of go up. Almost acts like it isn't getting gas. Any help is appreciated and I need it quick or I have to postpone my trip for another 4 weeks. Thanks.

 

How long has it done this, and is there anything "different" since then? First I'd add try injector cleaner in the gas. Then go from there.

 

It has been going on for 2-3 weeks now. After the first day we did it I tuned it up new cap rotor spark plugs plug wires all that and the coil pickup and all that I replaced was shot. I figured it would be better. I don't drive this that much so the tune up happened about a week after it started but we didn't drive it at all in that week. We tuned it up and now after one 15 mile trip it's acting up again. It seems almost to be not getting gas now not just losing cylinders. In fact I don't get that feeling t all any,ore just loss of power like I'm losing gas it happens then jolts itself quick back to life.

 

Sounds like fuel pump.

 

I was hoping not I just filled up for my trip. Lowering a tank with 40 gallons of gas in it will be difficult and time consuming.

 

Is it still missing with a full tank?

 

Dump some sea foam in the gas tank at this point.

 

Yes it is and I'm going to I have a can ready. I'm gonna run it with the seafood in it to the store tonight and to dinner and hope it helps or at least the fuel pump doesn't completely crap out on me if it is that while I'm on the road.

 

You might try seafoam... I don't think it would like seafood.

 

Damn autocorrect that is what I meant. Seafoam not seafood.
