well guys thank u guy i frist off want to say my spelling isnt the greatest i can read better than a can wright so please bare with me ok were to start well i have this stupid P0171 Fuel Trim System Lean Bank 1 oxygen sensor and a traction control/abs light i think that is due to the button is broken and no longer works ok well since that being said know this stupid lean code well i replaced a crank sensor+harmonic balancer ,maf sensor,cam sensor,icm,and pvc valve,fuel pump the old one was junk 20 psi idel 20 on rev up at 2k know it holds about 45 ish to 50 btw all brand new parts listed also i have check all my battery connections i am running a system so i have 2 extra ground thats 0 gauge so issue i have no power going up hill or on flat ground hardly its not the 3800 i know of its like im pulling a heavy load it is a series 1 3800 supercharged i also was checking for vac leaks i dont hear any but i am going to double check with carb cleaner or maybe soap and water in a spray bottle if that will be fine maybe i can make her sing to me and give me a new note also when i bought this car it had 130k on it and it know has 150k and its a 1995 Michigan car so im just looking for a extra brain just in case i miss something also sometimes the ses light blinks weird even with system off while driveing

This ., is called a period....I ran out of breath reading your post....

If the CE light is flashing, that means you have a misfire, and a P0300 should be set......the misfire could be caused by secondary ignition or a lean condition....

Have seen the gasket, between the SC'er plenum and the lower intake, crack.....this can be verified with carb cleaner, by specifically spraying that joint around the plenum, and watching O2 data or by creating a misfire/stumble at idle.....

As for the ABS light, you need a scan tool capable of reading "C" codes....most scanners/code readers can't.....

Thank you for all your help I do apologize for not adding periods I will try better next time

What scanner are you using to pull codes, and are you able to read live data?

Also, the abs/trac issue isn't due to a broken button. As mentioned, you will need to find out what the ABS code is, and that will likely give you a place to start there.

I used my buddy'* verus scanner snap on it, I don't know the model of the scanner. He won't let me borrow it for live data he said it'* a $ 1500 to a $3000 scan tool, and to be honest I don't blame him. Maybe I can get some time at the shop after hours to use the scanner for live data. So I'm just trying to find the power issues first, also going to rescan for any new codes as well since I'm in there already. I am not worried about the ABS light for right now, it still stops and barely picks up any speed to worry about. I have not checked for vacuum leaks yet, I will check that in a day or two with soap and water and a spray bottle. If I can get to the parts store I will pick up some carb cleaner since I am remote.

If I am honest, I would track down why there is no power before trying to track down vacuum leaks with a spray bottle. I would save this for if the code is still there after you find out why you have no power.

You could go through and check things like fuel pressure under load, ignition system, etc, but if you have a buddy with a $1500 scanner, it may be more beneficial to put him riding shotgun with the scanner to see what is going on. Most mechanical issues will provide you with enough symptoms observable with a scanner to help track it down.

Yes there is a detailed list of what i have all ready done includeing the basics like wires and plugs ect on the frist post i posted

Were all of the parts replaced in an attempt to resolve the primary concern, being no engine power?

If not, it would help to know when specific parts were replaced, and if it was in an attempt to resolve the issue.

I mainly ask because many of these are parts that won't usually cause a loss of power (unless you count a dead engine a power loss).

Also, what specifically was replaced when you did "the basics" and when? You never even mentioned anything of the sort in the original post.

I am mainly trying to get a bit more context on what is where, that'* all. For example, I am nearing 9 years of ownership on my '93 PA. In that time, a fair amount of parts have been replaced, some of which have been replaced an annoying number of times. I could list all of the parts when troubleshooting an issue, but once I put everything in context, most will realize the parts replace have no bearing (and in turn no meaning) to the issue at hand.

I try not to assume, because, well, you know...
