Tb-42e lumpy under accleration

Might just pay to go around all the chassie earth connections and clean em up.
possibly even add an extra earth strap back to battery from a good solid spot like starter motor Mt bolt.
not necessarily a fix, but a smoother engine is usually the result.

It appears there is corrosion in the fuel injectors, fuel injector expert tried a standard clean but too heavily contaminated, so he has taken them away for a more intense work over. Reason for this donor vehicle running old fuel from standing around.

Possibily cheeper to replace the injectors in the long run. After water ingress the fuel system will never be the same until you replace injectors and high pressure pump.

Might be cheaper than getting them cleaned. I've bought off them before, highly recommended.

Edit, for your information, the tb42e injector part number is JS21-1. I think the oem number is 16600-86G00. If you search the Internet, you can come across some great deals. Don't bother buying new ones off eBay or from nissan. They are expensive!

Cheers Parksy, see what happens tomorrow.

Miss fife now gone but running lean checked fuel pressure all good but delivery of fuel is low, new pump to be fitted.

[davo94]

Did you end up with new injectors?

[Pezzer]

No the specialist said apart from some stubborn crap they were not that old and that they were firing perfectly. However there was flow issue so on pulling the fuel pump out we found some debris had gone through a split in the strainer and damaged the pump.

Finally car all sorted all the above inclusive of a faulty MAF sensor, so much torque now it lifts the front wheels on take off. Hopefully a good weekend for putting the boat in the water.
