ya..... wow. interesting.....well im guessing the first 3 have something to do with the bank1 sniffer O2. the 1740 has stumped me. it happens when i go for a decent trip, say 40 miles. it will be fine 90% of the way then freak out and start misfiring the last 10%. it happened on the way to bass pro shops, i went in for about 2 hours (i love that store) then it was fine coming home till about the last 5 miles. same symptoms. weird.... it was snowing like a ***** that trip. hasn't happened the last 2 days at all, but i have not been going on any long trips. codes are still there tho. any input is appreciated, thanks again in advance.


P.S. => i will be ice fishing in lake of the woods, Canada, until Monday night so IDK if i will be able to reply to you guys for a few days, i might be able to on my iPhone, but God knows if i will get reception out there.

 

didnt you say that transmission is on its way out and you were going to have it rebuilt?

 

ok, im back from vacation. fox, i just had the trans replaced, then took it back in because they didnt replace something therefore not fixing it all the way. regardless, IDK how that would relate to misfires anyway.

 

im talking about your p1470... are you still experiencing the other issues?

 

no, the trans shifts fine, the fluid looks great, temp is good. i just dont see how that code has anything to do with the rest. i think i am going to reset the whole damn thing and see what comes back (if anything).


by the way the trip was a success. we were pulling in walleye and sauger all damn day. the biggest one was 30" and it was bagged by yours truly. haha.

nice catch.. yeah reset the codes, see what happens. at that point i would of just did a tune up and probably replaced the 02 sensor.

 

yeah, its a PITA tho and hopefully it will 'go away' until i get some long tubes or PPH's.

 

o 'm aware those o2s are a PITA... i couldnt connect bank 2/1 sensor into the harness. my arm is too f'in wide unless i took off the dist' cap and probabally the intake manifold, then i would of reached it. had to have the little italian kid in at my school last year climb up into the engine bay to hook it up. i swear those little guys do come in handy. even for tossing them around.
