96 850R cuts out and stutters when accelerating

Take a good look at your boost needle and see how far it goes before it cuts out. The 850 turbo is set to boost to 9.6psi which is still in the white. The 850R should boost to 10.5 and should almost clear the white. If you are boosting past this point and you get to 14.5 psi your ECU will cut the fuel off from the engine and the engine will fall on its face giving the driver a big buck. You mentioned that this car pulls harder than your last turbo. When was the last time or do you know if the vaccum lines have been replaced? A broken or leaking vacuum line to the wastegate will cause this.
Stage 0 is a good tune-up. It should include plugs, wires, cap, rotor, vacuum lines, PCV system, air filter, oil change and any other brittle hoses you find....and you will find some.
The spark plug gap of .026 is good advice. The .028 is the OEM gap and a smaller gap will help during higher boost.
Spark plugs, Champion RC7YC - cheap and work great.

All of you are wonderful, I just want to say that. So much information and so much helpful stuff! @rspi, I'll check those hoses today sometime. I drove it shortly for a bit yesterday, however, my girlfriend didn't feel safe with me testing the car so I only did it a couple times and the needle went past the white and it went there very quickly. But when I drive it normally it feels really good! Like... perfect!
I'm really hoping it's not a clogged PCV but it probably could use some cleaning anyway. It's always pulled hard since I bought it but after changing the plugs and wires, do you think that could have made it boost higher? I'm just trying to figure this out. I might have to wait to do all of this for a while because of financial reason, I may not get my tax return as planned (ex-wife) so yea. I was kind of planning of working on it with that money.
Anyway, I'll get to it soon though. And as far as the paint goes, I will keep it red, but it still needs a new coat. The wing is very faded, almost white one the top, and the R bumper and rear bumper have some deep scrapes from the previous driver. The one thing I don't like about my 850R is that I can't keep it forever and I probably won't be able to do everything I want to it (manual tranny). I love working on it and yes it does get annoying sometimes, mainly when I'm not expecting it. But it's a fun car for sure! I'm very happy I have it.

no, you probably have one of the hose unhooked. you are overboosting and that can mess up your turbo. it happened to me and now my turbo boost very low.l am looking forward for summer and l will remove my turbo, clean it and see if it helps bring the boost back.

Is your fuel pump relay good??
The last time I had this issue my halls sensor was bad in my distributor, so I replaced it but that was a pricy change.
Quick Hall sensor test: the tachometer needle does jump slighty as you crank engine over if the Hall sensor is working, but the needle lays dead if the sensor is not working.
In all actuality I have no idea if your year and make has this since it's later than 89!

That might very well be. I tried looking for them just with the hood open but I think I have to remove stuff? Sorry if I sound like a little kid. I also just went out and drove it and took a couple videos. I'm uploading them now and I'll post it here in a bit.

you lifters are making that knocking sound. how long has this been knocking like that? since you got the car? my lifters used to knock like that but l fixed it.it will knock its head off when warm. here is a video of mine,
this is after lifter change, and oil pan seals replacement.
the squeking noise is just the power steering pump that needs greasing. the lifters sounds quiet now

I need to put oil in so I think that's why it started today. I'm about to go get some oil. I'm getting a P0133 code now that happened about 10 minutes ago. I'll be checking that too. And I've been very easy on the car other than trying to diagnose what's wrong. I think I might have to clean everything out. I don't know how much it's all going to cost. And I need to prioritize everything. Should I clean the PCV first? or should I try and check the vacuum lines? This is obnoxious haha

No I don't hate the car. The truth is that I haven't really had the time to do anything with the oil. I only found out it was low within the past few days so I'm going to get some either tonight or tomorrow morning.
I want to be able to do it myself for sure, but I'm not sure how to go about doing it. I found a tutorial online so I'll look that over and see if I have the tools for the job. $700?? No way! I'll do it myself. I just need parts now I guess.
