94 318 rough start/ idle/ fuel cutting out
Hello all,
I am new to RF, new to Dodge, new to trucks..but my enthusiasm has only begun.
I bought the truck off of craigsist for 900$ cash. It has 91k miles on it (motor looked like it; no compression test was done) It has the usual 20 year old rust, an exhaust leak in the inter med. pipe, and a clean intake keggar. It drove great when I test drove it, and all the way home too.
This was to be my daily driver and possibly hauler (has towing lights/package already installed) at work. My usual car treatment began. Oil change, seafoam in the vacuum( only 1/3 can), full tank of gas, repaired small vac leak, changed spark plugs(look for issues mostly), and seafoam in the gas tank as well. Looked at the IAC (clean as a whistle), throttle body was too.
Then the last 211 miles have been treacherous. A rough idle began, missfires began (no fouling though), surging when taking off, not steady power flow. I immediately repaired the exhaust leak. She ran a touch better, but as I continued to drive her: she got worse. The catalytic converter began to rattle, suspect to a clog. IR Temperature readings indicated a clog, so I replaced with a magnaflow cat and new o2 sensor (******** never used anti-seize). About 1/8th of gas left in the tank, she left me high and dry in an intersection when she stalled out at a complete stop. It would not restart. I waited about half hour (40 deg outside) she fired up.. but seemed like she wanted to stall at any point when i slow down to stop.
Popped the hood, wouldn't start. The search began, as I checked spark.. it was there. Checked air at the throttle body, it had massive vacuum. Then I decided to spray a ton of starter fluid in the intake..she almost wanted to fire up completely!
Took my HVAC pressure reader, hooked it up to the fuel rail, when cranking it read only a spike to about 7psi...
Tomorrow AM, I am installing my new fuel pump and plan to lift the bed.
I think seafoam cleaning it of buildup clogged the cat, which caused the rough idle, to already weak fuel pump (guess the truck wasnt driven much in the last 20 years with 91k.) I hoping tomorrow she purr's after the new fuel pump..
Anyone have any other thoughts on my situation? I've never has this issue.. thought I got a needle in the haystack by getting a greak deal on 91k miles.
