Boggging/Lean Issue

[Coolhawk00]

So the other day I doing some random stuff to my car and went to go get gas and not too soon as i pulled out of the gas station the car started bogging and going lean. It didn't feel like a boost leak because I had just finished fixing a boost leak and I was at low rpm when it started bogging. Yes i put 93 in the car if that's what you're thinking. I thought maybe it had something to do with my spark plugs or fuel filter but I just changed both of those and no luck. Any ideas?

Being a bit more detailed than "random stuff" may offer a hint as to what happened. Did you do anything other than fix the boost leak? Did you remember to plug in your MAF?

Just a couple ideas...

I would also suggest back tracking all the "random stuff" that you did. What you describe, could be a number of things. The best thing to do is to start a process of elimination. Check injector connectors, i've personally been having some issues with at least one of them.

all i did was a boost leak test and yes i plugged the maf back in. would poorly gapped spark plugs have anything to do with this? I did change them a couple days before this happened. Thats the only thing I can think of.

Do you have an exhaust leak?

Yes your plugs could do this. If your plugs are poorly gapped you will see BREAK UP in your spark and can cause your problem.

I would check the plugs and regap them.

Also, when running higher boost sometimes you can blow the spark out and the gap can widen, so everynow and then its good to double check them and regap.

I haven't thought about the exhaust leak. I didn't think an exhaust leak would cause that big of a problem. I will check the plugs and look for an exhaust leak when I get home. Thanks.

Ok so I check the spark plugs and the second one from the right was over gapped so i regapped it and the one that was farthest right was gapped right but it was semi covered in gas. I clean them and check the injector connectors and tested it out. It was still a little lean at idle. Around 15.5 or so but it does hit about 11.0 at wot. It does however seem to go really slow now. It wont sputter but it is not as fast as it should be when at wot. I also go a little backfire sound as i shifted.
