if your datalogger reads constant but only the tach jumps, then it's probably the PTU.

if your car is actually stuttering, and your compression test reads low, you might have jumped timing.

Something may have come loose, check MAF and for leaks.

I had a similar problem
check your ecu wiring tach wire may be loose

i think its the injectors forgot to mention ive been driving lightly without air filter:barf: okay i know right stupid?! so i decided get some seafoam and put it thru the fuel tank maybe clean it a little bit than wam works fine few mins later same thing rpm keeps flickering! i checked everything nothings lose!
