Ongoing 99 7.3 running issue.
I have a 99' 7.3 with 547,000 on it. I pull a 40 foot trailer OTR with it.
Initially had a cold start problem replaced injectors 2,3,5 and 8 it started all winter without the block heater. Here in the last 45 days it started surging or jerking a little while under load at road speed and a what I call a half-miss on take off. Had 30psi fuel pressure had electric pump replaced and tank screens cleaned.
Still did the same replaced injectors 1 and 7 along with RB glow plugs and relay.
Ran good going out loaded started back same stuff coming back, engine shut off once at idle but retarted instantly. It also had to 2 cut outs at idle but didn't quit.
Loaded on 900 mile run truck quit at idle and wouldn't restart finnally restarted after about 15 minutes. replaced cam sensor next day ran good for awhile and then popped back through intake four times (at different intervals) and check engine liight came on. Stopped and shut engine off and looked it over restarted and light was out but has gone back to the sight surge at road speed and idle is a light rough, but no real miss as exhaust sounds steady. No codes stored when I check with scanner. KOER test no code half time and other half 0476 EBV performance.
Contribute test no code warm. The CPS I installed is the autozone grey one.
I haven't scanned this time will do when I get home. Any ideas?
