Default wierd 4k redline from time to time...

93 ka24de stick Allmost complete factory...(must of been owned by a mexican tho has a apc exaust tip)
just bought it the other day. test drove and drove home with not issue(3 hours)... last night i bogged down a lil and then the car died.(figured i ran out of gas cause i have no gas gauge) i put 2 gallons in it(all my lil red can would hold) then started right up. drove to the gas station and it would only let me put in like 16 bucks. this morning i figured i would try to get more gas. could only put 4 dollars in. i drove to the junkyard today to look for seatbelts. no problems there. left the junkyard and i died a block later. i got the car running(swaped relays around) started and idled fine. couldnt get over 4k rpms again. get on the highway to go home. after getting to fifth gear and slowly gaining speed i hit about 75ish. and after that ran fine on the highway. was able to downshift and go to 6kish rpms(not readline but around 6k) get off the highway to go buy a new headlight and the car dies on me at advance. figured it was out of gas again. added 2 gallons and it started up fine but then i couldnt get over like 2500 rpms. get home replace the fuel filter (took the pump out to replace that piece of hose and its a new fuel pump. replaced all the rubber fuel lines at the motor. get in car ran perfect. go to pick the g/f up get on the highway and left a mustang behind.(was a v6 and i bearly was taking him) get to her work shut the car off restarted like 10 min later and sputtered and died constantly on the way home tonight(died like 4 times and couldnt get over 35mphish)(no speedo so donno how fast but fithgear at 1200-1400 rpms)

any clue what could cause this???
im gonna be checking the maf tomorrow same with the tps. gonna try to clean out the iacv and there looks like there might be a hole in my plastic intake pipe(gonna take it off tomorrow and check)

i checked the codes. (got a vid of it)
11
12
14
21
34

11 - Camshaft position sensor
12 - Mass Air Flow Meter Sensor
14 - Vehicle Speed Sensor signal circuit is open
21 - Ignition signal in the primary circuit is not being entered to the ECU during cranking or tuning
34 - Detonation (Knock) Sensor

now i know the most of the sensor ones...(could they all go bad at the same time...) or could it just be a situation like the mass air flow making it run rich causing detonation so the comp assumes the csps is bad??? my timming might be off a few degrees... gonna try to get it to the shop to check it within the next few days(it only has one bold holding the dizzy down)
now for 14(i am guessing here) that could be the reason my speedo dont work being the sensor is bad or disconected...
21 have no clue what that is or what to do about it.

Cliff notes or else you have a 99 percent chance of no one helping you.

Are you getting shitty gas mileage also?

i bought the car yesterday... when i drove home(3 hour drive) i put 40 bucks in... i got home (160ish miles) went to my brothers then moms house. went to pick g/f up from work and died. figured i was out of gas(the float for the sending unit is gone) so my brother brought me 2 gallons. it started right up and ran fine. go to the gas station and it only allowed me to put 15 in. i figured it was the gas station cause all the pumps were in use and it took for ever. this morning i tryed to put 10 in and it only took 4. i drove for roughly 45 miles today. got home from the junkyard (with dieing 4 blocks away so i added 2 gallons thinkin i was out of gas.) got here and pulled the pump to find out i am so FULL of gas that it is spewing out of the part were the pump bolts to the tank because all the screws there arnt original...(when i find one at a junkyard ill be taking care of the screws...)

its the MAF
the rest of the codes are being thrown because the motor is bogging/stalling out.
get your hands on a known to be good one, then swap it out, should fix the problem.

oh, and to test to see if the MAF is an issue, just unplug it, take it for a drive, same/similar problems, then the MAF is going bad.

Or it could be something totally dumb like the plug is loose, which explains why it only gives you problems sometimes.
