I need an alternative! 1800 72

posted by  someone claiming to be Christopher on  Tue May 1 08:42 CST 2001 [RELATED]

I need an alternative!

1800ES in storage for 2 years but 2000 miles since march 2001. (6 weeks)

Had a problem with relay but now that I fixed that , I’m attacking the rough idle and misfiring at speed.

I have inspected everything I can think of.

This is not in order!

I have 4 new injectors.

The timing has been adjusted to 12degrees BTDC with vacuum removed.

I tested the compression and it’s steady at 150psi

I looked at the valve springs for cracks. Nope!

I re-gapped the valves.

I changed the distributor completely. (points and condensor)

I then changed the points

Then the cap and the rotor (twice)

The plugs (one was loose)

The plug wires

The throttle switch (twice)

The Computer

I have looked at the wiring and anchored it better than new (zip ties)

I still have errant firings. At “cruise” it tugs along with slight jerks then resumes to tug. It has power when accelerating but this might mask the misfires.

I would have thought that I would have stumbled over the problem or at least change the behavior by now. Nope!

I still don’t know if it’s in the Injection or the spark system but I could sure use some new ideas.

What if an injector is defective? It idles fine but at 700 rpm.

What would it do if I had air in the fuel delivery system? (I don’t see fuel dripping or on the ground)

On my drive to work this morning, it worked fine (cold)..... at lunch it went back to the "tug"(warm).

Can someone give me an alternative?

Thanks

Christopher
