Bumping this shit. Car started doing the same thing as to others. Didn't wanna make a new thread. So basically my problem is a tad bit different. I can rev past 3000 if I'm parked in neutral. But in gear it starts to bog. Won't go past 3000. This happened on the way to work right now so I haven't got a chance to look at it yet. ALSO, yesterday some street to get to my house was a little flooded so had to get my car in there.(nothing too had tho). Not sure if it's by chance that it happened today or not? Gonna go unplug my maf sensor and see what it does on my lunch break. The basic steps seems like, maf wiring > maf sensor > fuel delivery?? Oh and it's a KADE. All stock. 1993.

Thanks guys. Previous to reading this, I bought a zT-2 wideband O2(not hooked up) AEM Ems(not hooked up), Went through 2 sets of injectors, 3 MAF's, 2 fuel pumps and thousands of dollars at a shop to try and get my car running right(before i bought the ems, and the wideband.) anyways, I bought some 370cc injectors, am in the works of trading my tuned ECU for a stock ecu right now and plan on running with either an OEM O2 sensor(which i dont have yet, but i figure will eliminate more variables on my capabilities) or the wideband.

P.s. not a whole lot of money atm because of a move across country for my wife an I which is why I'm trying to see if i can get her fixed(the car) before winter which is why I dont just get the wideband/Ems tuned + sensors installed.

That fuel pressure listed above sounds exactly like one of my issues as I have Zero acceleration as well on top of my engine running rich and my engine's oil being mixed with Gas. I'm refilling with all mew fluids, and I just bought a Datascan tool as well as someone earlier suggested. Planning on getting this done Right, for the last time.

Heres my list of problems with my solution.

Lack of acceleration
Fuel pressure -> datascan/ Wideband
O2 sensor -> Wideband/ purchase new
MAF -> Datascan/wideband - clean.
Tune -> For now OEM Ecu dont have to worry about tuning
Clutch Slip -> New Clutch
TPS -> backup one

What do you guys think?

The fact that nothing changes when you unplugged the maf could point to faulty wiring or a bad sensor entirely.

Bump
Car will rev past 3k in neutral but once in gear its like I have to keep the clutch in a tiny bit and baby the gas or else the car will bog. I turn off the car for a while and then it works fine for like 10 minutes of driving. Wondering if its the TPS

There's no need to bump the thread with descriptions of the same problem.
Especially if you haven't done anything to fix your issue. Pull codes!
No codes then its not a sensor issue.
Could be fuel or fuel pump. Timing is going to be jacked have you checked that.
Or just post
Tell me how to fix my car!
Or would you rather have people quote the same suggestions that you should have read like I did.
