Running Rich and idle problems

[Carolyn]

Is there any kind of a 'seal' for keeping out dirt in storage?  Something physically blocking them?

[M.Dub]

Iv had the same thoughts but it's hard to see. It dose look like somethings in there but not sure if it's suppose to b or not.

[Carolyn]

Perhaps contact MAG and see if they use anything to seal them?  If they do, and they've been exposed to full pressure fuel...

[M.Dub]

I already have contacted them but not holding my breath tbh.

I'm pretty sure they've had full pressure at them. I'm guessing that's bad?

[M.Dub]

Lol you mean I will never get them out?

[M.Dub]

Is there any way to add a video clip?

Iv tested all the new MAG injectors along side some old ones and hooked them up to a battery. I can hear the solenoids operate in all my old injectors however the MAG injectors do nothing at all.

Generally people upload clips to YouTube or upload it to a online drive and link it.
Unfortunately we can't afford enough storage to accommodate people's videoclips

A simple check if you have a multimeter is to check the resistance of the injector across the connector pins.  I checked a good set of green injectors and got 13.6 ohms on all of them.  The Toyota spec is 13.4 – 14.2 ohm at 20°C (68°F)

Funny enough I tried this out of curiosity only checked 1 of the MAGs it was 29ohm

Sounds like they sent the wrong injectors.

That's what I was thinking.  They sent me the wrong pistons once.  They put it right and I ended up with two sets of pistons.

Very odd that they have the same part numbers. 
Unless mine are wrong as well

[M.Dub]

Even if they were the wrong ones for the MR2 they should still open when connected directly to a 12v battery?

Iv messaged them so hopefully I'll get a refund or another set sent out.

Honestly tho, I'm sick to death of changing injectors I never want to do it again!! 

Hopefully 4th set lucky

Don't ever touch my car, please 😀

😂😂😂

[M.Dub]

Just for the record It's all the parts fault

[shnazzle]

Mine are all 14

[M.Dub]

Iv managed to free 2 of them up by just persisting with the battery so they now open and close, not that I'm planning on using them id just thought I'd let you know.

[jonbill]

I suppose its possible they are coated inside with some anti corrosion goo or something and it needs to get washed off. perhaps soak them in petrol?

[Carolyn]

I think some plastic film has got shot into them.  Maybe just soak them in petrol over night?.

[M.Dub]

Had a response from MAG, they acknowledge there may have been a problem with the injectors and are sending out a new set.

Good service from them in the end 👍

[M.Dub]

I must admit I'm not convinced that installing these injectors will fix the issues I'm having, Iv got a feeling it's something more sinister.

If these don't fix it given Iv exhausted all the simple options what else could it be and how would I diagnose it?

If 2 cylinders keep misfiring all the time and the other 2 misfire rarely given all 4 have similar compression, new plugs,good coil packs, new injectors, Iv check the electrical connectors.

What could it be?

I'm mindful that the engine has previously undergone a rebuild and concerned its something internal?

Thanks

[jonbill]

you could check the cam timing.

[Carolyn]

Have you checked the valve clearances?

[M.Dub]

I haven't done either of those, Iv never done anything like that and don't really have a clue how to do it.

Is it something I could do myself with some Googling? Are they difficult to do?
