Ok here we go 05 100xxx stock everything except mid pipe and cel is on but because of midpipe and I know that forsure.. Not flashing or anything. ran perfect before I stored it for the winter went to get it out of storage and it was flooded... Got it de flooded cleaned plugs put them in fired right up. They were new plugs and coils right before winter. Now car starts fine but when I'm driving it and give it just a little gas its sputtering back and jerking back and fourth until I shift into higher gear and Rpm's are lowered then runs good ( but not suppose to drive at that low rpm). What I'm confused about is I have all the power I have always had and if I bang through the gears almost redlining ir runs fine. Just when I'm cruising and press down just a bit on gas (like regular driving down the road) it's sputtering. And sometimes when I let off gas rpm with drop down very very low then back up to about 900. Sometimes even shuts off. Idles at about 8-900 and a little bouncy. Cleaned MAF, reset ecu new plugs coils(before it sat all winter) the only thing I have yet to get is plug wires. When I was de flooding I noticed on the plug side of one of my leads the metal cap that snaps on plug was bent so I grabbed needle nose and bent back to snap on. Is that my problem? Could it of broke in the elbow of the wire/lead ( whatever you'd like to call them). A lot to read sorry but I'm waiting on my wires and if that don't do the trick I'm not sure maybe ssv? Or fuel pump? FP filter? Or something else. If anyone could help I'd appreciate it thanks.
If I left info someone needs to help me out sorry I'm sure im forgetting something. I always checked for vaccume leaks and all looks good.
she still rips as it always has and I don't have rough starts or anything.

Bump. Replaced leads still the same.. Maybe ess? Or fuel pump sock/filter? Need some help here guys

Can you get the codes read? The problem with allowing the cat code to be persistent, is that when other CEL's show up you are unaware. And throwing parts at it without diagnosing is kind of a waste of money.

Just got it read today again and it's P2070 and MAF I cleaned MAF with actually maf cleaner and noticed rubber o-ring getting bad split but not broke yet I should have one same size I'll put on. But the p2070 is ssv? Looked it up a little bit don't seem too bad but would that be the prob. Most likely? And yes I'm well aware of throwing parts is a waste of money. The parts I have replaced I have acquired over winter while its been in storage for a tune up...

Check this thread seems related especially with sudden power loss..

Ok took ssv out cleaned it and seemed like it was moving decent when I took it out and was not terrible dirty. Don't make fun of me for the next part but put it all back together and it's still doing it and I did not even think about checking the actuator/vaccum selenoid to see it'll that was bad and causing it not to open? I have no oil in my intake tube and never have so I'm thinking it's the selenoid? And it's the same as the other 2 by it so I could swap it out with another one and try it right?

Devin802

Sorry for double post not sure how to edit ( if you can) and busy at work but when driving the car feels like it's not even trying to open or open a little bit so I'm guessing it's the vaccine actuator thing. (Don't know correct name)

has the code come back for the SSV?

And, have you reset the ECU again? If it learned to run with a suck SSV, who knows what it is trying to do with one that works.

I reset ecu and havnt got the cel checked yet I'm waiting to get my rubber o-ring for my MAF then I'll get it checked after I throw the new rubber ring in.
