I am sorry but you description is hard to understand. Can you be more specific as to what the problem is? When you tightened the intake system did you use a torque wrench?
Customer: replied 4 years ago.
i tightened all the nuts with a flat head and changed the mass airflow sensor. the truck has been sitting for about a year while i was deployed to afghanistan and wasnt taken care of. when i crank the truck it back fires and putters and backfires at about 1000 rpms. and then will either just shut down or spike to about 6000 rpms and it sounds like it is sucking in way to much air when it spikes.

How much gas did you leave in the tank? If you take the gas cap off and smell in the filler neck does the gas smell rotten?
Customer: replied 4 years ago.
a quarter tank of gas... i also poured in barely any lucas injector treatment to see if that would but nothing, and the gas smells a little off kinda like not how gas smells when your pumping
Expert:  kalamykid replied 4 years ago.
Do you have a fuel pressure tester? The first thing to check will be the fuel pressure. If the fuel pressure is good then we will have to go from there.
Customer: replied 4 years ago.
i dont have one at this time but i at least know that the engine is getting gas and the pump works
Expert:  kalamykid replied 4 years ago.
But if old gas sits in the fuel pump it can damage it and the fuel pump will not be able to create enough fuel pressure for the injectors to work correctly. Do you have an auto zone or an advance auto parts near you? If you do you can rent a fuel pressure tester from them and when you take it back they will give you all your money back. I really need to know the fuel pressure to be able to help you fix your truck.
Customer: replied 4 years ago.
ok, i will get one and get back with you, thank you for all your help soo far
Expert:  kalamykid replied 4 years ago.

If you would like me to i can send a response with the answer button so the accept button shows up on your end, but that is up to you. I would rather wait till I have given you a good answer to your problem first.
