Asked by Feb 22, 2014 at 05:58 PM about the 1998 Dodge Ram 1500

Question type: Maintenance & Repair

I have a 1998 Dodge Ram 5.2L ( 318 ci) that dies when you give it gas..
It wouldn't run on damp days so I changed the d-cap, wires, rotor and plugs and it seemed  
to fix things, took it for a good drive and parked it. About a week later I started it and it
fired up fine but when I raved it up it would lose it's power, almost die and the smoke
coming out of the tail pipe was really black.
I changed the coil, didn't help, changed the throttle position sensor, manifold absolute
pressure sensor and the intake manifold air temperature sensor, filled the gas tank up with
high test and put a liter of alc and nothing has helped, the more I run it the worse it gets.
It starts fine, has great fuel pressure ( 49-50 psi) and there are no lights or codes coming  
up but when I give it any gas it bogs or dies..
Does anyone have any advice.
Thanks.
Zach.

The fuel pressure doesn't drop at al,l it stays between 48.5 - 50.5 psi and dealer specs say it should be 49.2. I filled it up with high test and put a liter of 99.9% alc and a a small bottle of injector/ line cleaner in it and let it idle for about 2 hours and it didn't change anything. I'm going to try the Idle Air Control Motor tomorrow. Do you have any other ideas. Thanks. Zach
