2004r Trans Problem? Maybe not?

[mr evil]

Yesterday a buddy came over and helped determine that it is most likely a fuel problem. We bypassed the tank and lines with some redneck technology, same result.

Changed to a hotter coil and new cap. I was able to get hold of a non cc carb in known working order, so today I will pull plugs, change pump and change carb if need be.
We are thinking mixture solinoid on the existing carb maybe the culprit, but I will eliminate the easy stuff first.

I'll post results either way.

The problem is getting worse btw. It fully stalled out a number of times yesterday. Give her gas, she jerks like starving, then dies. Pump and crank a few times and she rolls again until you step into it too much, then dies again. Like carb is running out of fuel.


Lol, in the process of replacing old vac lines I came across a nifty little gadget. It consists of two plastic encased magnets that stick together around the steel fuel line just down from the carb. I'm looking at this thing thinking WTF is that? Never seen that before. So I take it off and read it... 'Super Fuel Saver' lmao! Nothing more to it than a magnet. Some moron before me actually bought into one of these! Unfortunately, removing it did not fix my problem.

pull a plug, if it's black and/or wet you've got fuel, if white no fuel.

I agree with kustomkyle about the cat. I had a mid 90s truck that did the same thing on a long road trip. It was fine if I held it to the floor but wouldn't cruise at low rpms and wanted to stall at idle. I ended up buying a hacksaw and putting in a pc of pipe because the shop where I went said it was 400 plus install for new cat.
Might be getting fuel in just having trouble blowing exhaust out.

Swapped carbs, seemed to fix the problem. I guess the other was done :wink:

Thanks for the input guys 😀

it's not as easy as it used to be looking at the plugs....with the ethanol filler in our gas the plugs don't have the same color they used to... depending how much ethanol the ethanol can turn the plugs a whiteish shade

ethanol never gave me a problem reading plugs. outside of a $400 A/F meter it's still the best way to go.

mega..I have one of my client who owns a shop where they do emissions so I can run my into their shop and they'll tell me exactly what the fuel mixture is at various rpm's...but I do find that ethanol does lighten up the color of the plugs and I found that out by the guy who builds my carbs and alot of other carbs for circle track cars. Perhaps we run more ethanol in our gas up here that you do
