Sudden death on highway.

[Mr. Burns]

Checked injectors. Visually okay, no leaks or fuel odor.
Cleaned afm.
Visual inspection of o2 looks okay, haven't pulled it.

Fuel filter was however dangling. Placed back up with the plate in place, strengthened with tie wraps.

I have a spare ecu I can throw in the mix if need be.

Also visual inspection of rockers are fine too.

Would bad coolant temp sensor do this too?

Car only fks up at running temps.

Similar issue happened to me. Ended up being a bad AFM

[Mr. Burns]

Taking day off work ( I work for the Feds) and will get to bottom of this.

Current time is 755 am. Grabbing coffee and headed to pnp for parts.
Gonna be a good day.

Dme is my guess

[freeride53]

Sounds like how it TWAS when my fuel-pump gave, and my fuel filter was also clogged.
Replaced both, BAM.

Similar thing happened to my friend on the freeway. He was cruising at 65 and his power cut off completely. It ended up being his Fuel pump.

check fuel pressure and lines. also check the injector harness connector under the manifold for corrosion or other nasties

[AndrewBird]

Could be a vacuum leak. I would check for tears in the intake boot. Pull it off and flex it back and forth and look for any cracks.

Cps??

[Cronopoulos]

Fuel rail pressure.
Can this be checked with compression tester?

A different tool (Fuel pressure tester) must be used.

[Raxe]

Check the filter, may have damaged it internally or crimped a line somehow.

Wish my E30 had a CEL.

[Mr. Burns]

As stated above a 1221 (or a 1222) code can be the result of an upset in the A/F ratio. In this case my first suspect would be a fuel system problem since the engine will start but not run well above idle. A check of the rail fuel pressure would be the first thing I'd do.

[Mr. Burns]

No. Still too warm to meddle with exhaust. Will wait till tomorrow.

[nokincy]

Have you tried running it with the O2 sensor unplugged?
