Injector cleaning vs rebuilt vs aftermarket

[spavel6]

My 1993 Eurovan with the 5-cylinder Audi gasoline engine has been running lean, heating up the cat, backfiring (infrequently) on downhills, and generally low on power. I am suspecting that it is finally time to clean the injectors to restore the spray pattern.

(By the way, new coil, spark plugs, O2 sensors, plug wires, cap & rotor, catalytic converter, lots of PEA-based cleaners through the tank).

Thoughts on pulling the injectors and:
1. sending them to a local shop
2. buying GB rebuilt injectors on RockAuto
3. buying AIRTEX/WELLS new units

Anything else that could be going on?

Have you checked and replaced the fuel filter and checked your fuel pressure to make sure it's not a dying fuel pump or restricted filter?

Buy the new ones

eBay item #191550476284 might also work for you

Get in touch with Trav. Even if new injectors are required, you'll sort everything out.

Send them to Trav, he's 45 miles from you.

He's got 6 injectors right now for my Jeep that he's re-doing.

These are old side feed injectors and don't clean up very well from my experience, many die during testing when the rpm's are turned up. Do not by GB or AUS remans, they are notoriously poor quality.
I would get a new set for this one if they are really bad. The Wells are a decent injector, at least Rock has 3 of them so you only have to source a single.

Edit: I would love the work but honestly cleaning is not the best course of action for these particular injectors. Thanks guy for suggesting me.

How long can your vehicle be down? Trav is the man. Got multi port injectors awhile ago to replace the single port injectors in my Jeep Grand Cherokee a few years ago from him.
