Possibly dirty or clogged injectors?

 

FWIW, what is your TPS voltage showing at WOT? I have had multiple TPS failures and sometimes the voltage at WOT is like mid 3.0 (should be 4.5 IIRC), so WOT the car woulf think it was at like 80% throttle and it would run piggishly slow

As expected, I replaced the plugs with a set of BKR8EIX Iridium plugs and now she runs good as new.

Thanks for the help guys!

Edit: Nvm, still doing it.

 

Good to hear. How did the ones you pulled out look?

 

Yep. Definitely a relief that it was something so small/simple.

Very dark brownish. Wouldn't say black though. Definitely older than I thought.

Going to start to keep a log on Google docs of my maintenance. Hopefully should prevent issues like this with my horrible memory.

 

Apparently I spoke to soon... I could have swore it was fine, but its doing it again.

Now I'm thinking it may be a clogged injector, because it is running VERY lean, and the tune is the the same as it has been (worked fine for plenty of miles before this). I was surprised they didn't clog after I switched to E85 considering we don't have a fuel filter... The injectors themselves don't have many miles on them, but I can only imagine how much crap the E85 must have broke loose after ~50k+ miles worth of 93 being run through the fuel system.

Anyways, I sent a log to my tuner. Will wait to see what he says. But chances are very good I'll be stopping by USPS in the morning to mail off my injectors for cleaning...
