Can I just say how ****ty it's running is very odd lol?! It's not consistent. It runs up to 1800 then falls on its face, as if the engine shut off. Then it recovers if I cut the throttle quick enough. It surges at idle after revving... And the cold start problem on top of that unless given extra fuel. Is there any other sensor/part I should be checking? Idk guys... As I said I'm going to get on the waiting list for a marina, but I really want to fix this myself.

OBDII diagnostics has a scan tool for a laptop that will apparently read all the same data a Rinda tool will, for 180 bucks versus 700. Any thoughts?

Could you post the injector model and brand of the type you just put in.I would not waste on more penny on parts this is a injector problem or ground

TG - you changed your name! I would post the original ones, but I can't find the part number. It's non existent on the injector.

The new injectors are Standard TJ11's

Guys - one more thought. How expensive/realistic is it to switch to MPI? I am willing to spend around 1k to convert to a full MPI setup if you all think it's worth it.

It's not wasting $$ on this set. Just shipping 2 states away. Cheap.
The last set...we'll see. Could have been a waste.

So rock auto had three injectors listed. The TJ11's didn't work (unless something else is wrong). That leaves two more. The 500-2016 injectors are described as "5.7 gsi" under the application. They are walker products. The issue is I can't find that part number in the walker product catalog. I can however find the last injector listed on rock auto - "500-2000". Rock auto doesn't give a description, but the walker catalog only gives V6 volvo injector part numbers. Then right at the very end of the volvo Penta injector guide, it lists no model, but lists 5.7/V8 1994-2007, and the "500-1136" injector next to it.

I know it sounds crazy, but should I buy both the other sets from Rock Auto if your suggestion doesn't work SB?

Lastly, I am about to buy the MEFI burn scan tool, rather than the Rinda tool. Is there any reason not to?

If you guys think the Rinda tool is worth it, I will buy it. It's an investment in the future as well.

I can probably get it in to a local marina (mine won't work on Volvo Penta), next week. I don't have any certified Volvo shops near me, unless I trailer it there. Most want it in the water. I know experience counts, but with the proper tool (Rinda Diacom), I feel pretty confident I can pinpoint the issue. The only question is should I wait for my new set of injectors first. I know I am getting antsy and that's never good for a wallet.

OK i believe the injector your looking for is gm 852956, a little more research needs to be done but that should be the right injector. I need to find the spec's for that part to confrim it however it can be crossed referenced to STANDARD MOTOR PRODUCTS Part # TJ17

nunnink23

TG, where did you find that? I did a little digging today, and I am thinking that the OP in the post we referenced earlier had bought one of the two walker injectors.

I won't have time to read these until later, but it looks like the black/yellow injectors are indeed the right ones.

SB - are the ones you're sending black/yellow style?
