02 1.6 Intermittent poor first gear acceleration - dave_s
Having had one problem solved on here today, thought I'd try the other one. My 1.6L 2002 Ford Focus Zetec has developed an annoying intermittent problem - only happens maybe once/week.

Will be stopped at traffic lights/roundabout, and when I come to accelerate in first gear it just doesn't accelerate - moves along at about 3-5 miles/hour for about 7-10 seconds before kicking in. This is with the clutch fully out. Pressing harder on the accelerator doesn't make any difference. Engine doesn't over-rev. Just doesn't accelerate for a while, then suddenly off it goes.

Has been going on for about a month and has happened maybe 5 times - no obvious cause, no funny noises. Pretty dangerous when it happens on roundabouts though - any ideas?

Likely to be the throttle position sensor causing this and will need to be replaced.
