I have a 95 s14
K so my car is ackin up. When i hold the pedal at 1000rpm the needle will vari about 200 rpm then smooth out till 3000 and even when i full throttle in a low gear it will maintain speed and even start to buck. K so hears what I checked
1. timing is dead on, yes i did the sequence

2. Vaccum checks all good

3. Compression all perfect every cylinder

4. new maf

5. new Throttle position sensor

6. new fuel filter

7. Fuel pressure perfect

8. New cap plugs and rotor

Only trouble code i get is crankshaft position sensor and we all know how usless that is. One thing i noticed was when running the timing light and accelerating the timing light wasnt smooth it kinda skipped or sumtin anyone????

 

hows fuel pressure?

 

Did you check timing chain?
How many miles?

 

did you try spark plugs lol?

 

Its a "rebuilt engine" so dunno bout the mileage but i mean compression was 170 so must be fairly new

 

you said you have a new MAF, have you disconnected your battery to reset the ECU so it will recognise the new MAF?

 

Well I disconnected my bat for an hour and changed plugs to iridium copper instead of those four prong kine and it went away!!!! Idk which solved it but thanks guys

 

i told you it might be somethin like plugs. always start with spark, timing, and fuel when you have any ka problem

 

Ya now only if i can figure out why my wire boots keep poppin up?

 

check to see if your spark plugs are loose.

 

don't torque the plugs in too far. maybe it's time for new wires/dizzy rotor?
