Stuttering/Hesitating Under Heavy Throttle

[nort0188]

1993 V6 - Once everything gets warmed up and driven... maybe 15 minutes into a trip, whenever I lean into the throttle she stutters on her way up through the rpm's. If I floor it in D it'll attempt to downshift, and then give me nothing at all for a few seconds, then it'll kick into gear and go. If I have it in 2 or L and step on the gas, RPM's will climb slowly and very unsteadily, with much less power than normal. Initially I thought it was something with the ignition, but I let her sit for a few hours with the hood open and cool off, then took her for a drive and everything was just dandy, so now I think tranny... maybe it just needed a chance to cool down? Anyways, I'll check all that out this weekend... until then, anybody have ideas of what else it could be?

Sounds like a misfire. Maybe a bad coil.

Yeah, sounds like a misfire to me too...

Check each plug as well as the coil.

Plugs on a V6.... BOOOO! I know where my Saturday is going

i had something similar, was the fuel pump

^ that's what I was thinking

Was changing the plugs today... the reachable ones at least... and one of my wires is bad. The metal part inside the rubber that actually snaps onto the plug is completely seperated from the wire. I pulled the wire out and it was still down there attached to the plug. I sure as hell hope thats whats causing it, although I really doubt it'll be that easy. We'll see tomorrow when I change the wires and the two impossible plugs.

^ That'll do it.

Its running on 5 cylinders instead of 6.

I'd check the other plugs and wires like you said and go from there.

It felt so slow yesterday when it was doing that.... I can only imagine having a 5S-FE

Of course I've got to upgrade during this.... going from Bosch Platinum to Bosch Platinum +2 plugs

I have the same problem on my Camaro, I put sta-bil in it, and it ran great for a few hours, did some victory burn outs....got home, ate lunch,took her back out and shedded a belt. Since then...shes been running like pure crap and the for sale sign gets closer to her window. Camaro ='s top of line Camry suspension.

SOLVED!

It was most certainly the plug wires. Two of the wires were seperated, as described before. Changing the plugs on the rear bank wasn't TOOOO bad, although it certainly was not my idea of a good time. My suggestions to anyone who plans to do a plug change on a V6, make sure your spark plug socket will also grab and remove your plugs, and wear gloves! I really don't think there would be much skin left on my hands were I not wearing gloves. Thanks for the help guys!
