Outer Limits 4x4 Board

Hi had my current injectors cleaned (properly) and a new fuel filter and all that stuff and I didn't notice much change, these days I am getting more frequent problems with power, idle and all the rest so I have come to the conclusion that the injectors must be stuffed.

Does anyonwe know the approx cost for 4 new injectors and can suggest any place to get them?

I would also check compression.... then tappet's.

and the oxy sensor...

Particularly if it is surging.

an check valve clearance, readjust if needed.

Just wanted to get everyone's opinion on what might be going on with my vehicle now. I am still getting intermittent harshness at different revs/loads and hesitation within the first minute or two or warming up. I also get rough acceleration when I have moderate to heavy throttle as well as rich smells every so often.

I am still thinking I have injector problems because I have had the engine rebuilt a few months ago, a new oxygen sensor, leads checked, timing is fine, valves adjusted correctly, new filters, vacuum checked, distributor checked.

The injectors have been cleaned and that introduced new problems which makes me think it injectors even more.

I am planning on doing a injector spray test, pressure reg test, and flow test soon.

What about fuel pump?

Who cleaned the injectors? They should have done a spray pattern check and checked the flow rate when they did them.

Have you checked if the oxy sensor is earthed to the battery negative?
