Engine acting up - The Ford Focus Forum

**marcusfranz** · 11-03-2009, 07:15 PM

When driving a i can accelerate up smoothly but when say i floor it from a stop it goes...

pop-pop-pop really fast for a while then catches up its like a machine gun.

any ideas what it can be, i already did the egr mod thing.

It happens worse in turns.

Its not the tranny poping its the engine like its missing. Could it be fuel pump?

Add some fuel system cleaner, cleaned maf, cleaned throttle body, cleaned and re-gapped spark plugs.

Problem is going away, i suspect the fuel injector is doing it as its getting better the more I drive, only driven like 30 miles since i put the stuff in so hopefully its doing what its supposed and everything will start running like new again soon
