Car pinking/missing/spluttering

[flev93]

Hi, my first time posting here..

i own a 106 gti on "x reg"

when i bought the car it had a the same problem, it seems to happen at the same revs in ever gear, car just seems to die around 2500-3000rpm, and splutters, but if i put my food to the floor the problem goes away and car picks back up as normal.

since then i have fitted a jp4s engine.. and bought another j4 for the inlet, cams valve springs etc..

i used every sensor of the donor j4 engine, so i used map sensor, icv tps temp sensor, coolent sensors knock sensors oil level sensors changed all of them.

and yet i still have this missing or pinking if thats what its called.

ive also changed the, injectors, fuel pump, spark plugs, lambda sensor, fuel relay, fuel filter.

only thing i have to change is coilpack then i have changed everything over ont he engine bar the loom and ecu.

anyone got any ideas because its driving me mad!

thanks in advance.

Try ebay mate I had to buy one last week as I'm having running issues, I've changed map sensor and plug, spark plugs and coil pack.

Think I'm going to look at the injectors
