Hi there. Living in Norway, so ecxuse my english

I`m have a problem whit my S10.
Its starting whit a loose wire/ plugcable on #4.
I put that on, and now it`s run on 3 cylinders...
Actully it`running on all four, but #4 are wet of gas.
I have read a lot of threads around, but nobody came up whit a solution.

Allready checked the coilpacks (bougt a secondhand for refference, 1-4)
cross-swapped 1-4 and 2-3, new sparkplug on #4
swapped wire 1 and 4.

Have god spark on every coil, whit wires on
and directly on the coils (put a small piece of rubberhoose
on top of the plug, and a jumpstartcable too negative on battery)

Then i read something about a injector was stuck open.
So I removed injector #4 and and put it in a Transsonic 310 for 2x15min.
Same problem, wet plug....

Have power in the cables, LED light 12V tester,
and a small click in the injector then I put 12V on it.
In a atemt too move the problem I swapped injector #4 whit #1.
Same problem, plug #4 still wet of gas.

So I running out ideas what it could bee.
Btw, i have 130psi in cyl #1 and 4, and 135psi in 2 and 3.
And the car only have 125000km on the road...

Anybody who have any ideas?

Best regards Morten from Norway

 

Think I found the problem.
After swapping injector 1 and 4, and have driven it around for a couple days
plug #4 is dry and ligth brown again.
But now is plug #1 wet, so it`s seems to be the injector.
Bye a new one or a used if they have in the local us. scrapyard

 

Good luck hope it fixes your problem.

 

Yupp. Fixed it now.
Ordered 4 injectors on Ebay and put them in.
Fired right up and run smooth now.

Notised there was som different partnumber on the new ones,
the old ones had something and -9130 in the end.
New ones had 2x -6116, 1x -6130 and 1x -9130.
Altso tree different numbers....
Something to do whit opening times?
