97 j30t slow idle , many codes

[elciclista]

Hello everyone;I'm new here and have been searching the posts without luck.I have a 97 j30t 74k miles.New air filter at 71k. It's been running beautifully getting 20 to 25 mpg. Went on a trip, drove 180 mi. to my destination, fine, on the way back drove 80 mi. fine, filled up with mid grade fuel ,they were out of premium. drove the last 100 mi. Stopped to pay toll noticed slow idle, did not worry. Got home turned ignition off, then cranked it up again. Now I got engine light on . Borrowed code reader and I freaked. I got: p0505, p00443, p0135, p0141, p0155, p0161, p01400, it's idling at aprox. 400 rpms. while in park I accelerate and it seems a little rough at about 1000 rpms ,but has plenty of power won't stall but feels like it wants to, when starting out. My question; Could cheap gas have caused fouling of plugs and or injectors and therefore the codes?, or did a whole lot of trouble just decide to show up. Any help and or suggestions would be greatly appreciated.

Hey Thanks for responding. Yes, I'd like to give it a shot before getting a second mortgage on the house to have it fixed.

Kinda bizzare it all popped up after a fuel up.Could a boatload of water in the fuel cause those ?Just curious.

That's my confusion. I can't help feeling there is a connection between my problems and the gas. You think I should try some injector cleaner to start?

A can of HEET and some BG44k surely wouldn't hurt !!Heet will solve any water issue and BG44K is the best fuel system cleaner on the planet !!
