Hi all . Been a fiesta 1600 si 16v owner since i took delivery of a sparkling new one in 1995- trouble free and great times all the way (well nothing major) but now approaching a well serviced 100000 miles have picked up a problem . when pulling away or reving engine get loadsa spluttering and no response when put pedal down , ok when feather throttle down gently and build up rev's , occosionally cuts out and have to turn off and restart no problems ????? done plugs /leads/fuel filter .Cleaned MAS /changed air filter reset ECU ??? gonna go for Crank sensor next tempted by changing coil -distribution unit . any thoughts as i can't bear to see my old girl like this .

and its starting to drive me nuts

..... and i wished i found this great site ages ago well done to all .

does sound like an ignition or sensor fault
i'd say you have a choice of:
Maf sensor, unplug it and see if its any better
TPS(throttle position switch) could try cleaning it
Coilpack, replace with new one
Lambda sensor, replace with new one

sussed it .... got use of a garage for a day or two so gave it a going over ... and would you believe that the new plugs i bought where faulty and 2 had an intermidiate fault and reluctant to spark under heavy load and no better then the knackered ones i took out (ok when slowly building up rev's) ? bought some better quality plugs (me thinks i should have done this in the first place ) fitted and problem solved . off down to hellfords to throw each of them in turn at the parts dept .

. i think you can guess what make they where . theres a lesson in here somewhere :lol:
