Fuel injectors

[84GNGary]

Got 42K on my stock injectors and my GN is completely stock. Should I replace them or remove them and have them ultrasonically cleaned. Also do I have to remove the turbo to get to them.

are you having any problems with them ? i have 103xx on my stocks and they are still working fine.

If you do not have any issues with them I would not touch them unless you want to upgrade.

I get some hesitation when I start out hard. I have not driven it at all in the last two years and very sparingly in the last five years. I left gas in it without adding stabilizer for the last two years and I have done this before then too. That is why I was thinking about doing something with them. I did get all the old gas out and put new gas in it with Gumout fuel injector cleaner. I did replace the plugs, wires and all the vacuum lines about five years ago and if they have 100 miles on them their lucky. But I have had the hesitation for over five years now.

I would try resetting the IAC and the TPS to make sure all of that is in order.

dump a small bottle of Marvel Mystery Oil in the gas tan kwhen it's only got about 1/4 tank and run it. that will clean out the fuel system pretty effectively. i know it made my 94 Caprice with 200,000 miles on it run better just by dumping it in the tank.
yeah- it is snake oil, but it also works. and it's cheaper than any other good cleaner out there.

I readjusted the tps to the proper output voltage and the hesitation went away. Although I did notice a dead spot in the tps when it checked it with an ohmmeter, if it acts up again I'll just replace it.
Thanks for the help.
