I think I'll just take it to the shop. Have them hook up the scanner and do a fuel pressure test. What psi should it register to be normal?
Oooops. 97..... that makes life more interesting. If you want to do it yourself, you will have to build an adapter that goes between the fuel line, and the rail, that has a test port on it....... Otherwise, have to pay someone else to check it. Not sure which way would be cheaper.....

Tach gets its cue from the PCM. If the crank sensor is failing, you are more likely to notice the engine running bad first.....

I have a 1997 Dodge Ram 1500 4x4 with a 5.2 318ci, it has an issue where randomly it almost stalls out and bucks and jerks at steady speeds until it's driven for more than 45 minutes than it'll be fine until it fully cools down again shifts fine thru all the gears does it with o/d on or off. I've replaced the iac-idle air control valve. Tps- throttle position sensor. Map-manifold absolute pressure sensor. Ignition coil plugs wires cap and rotor. No vacuum leaks I'm lost any help would be appreciated.
