I come accross this forum and I hope someone will be able to help me to solve the problem.
I have a ford fiesta '93 1300 cc 60 hp with 160 000 km.
Cold engine : As I try to speed up, the engine ( at 2500 rpm) is like someone having a cough...
Warm engine : The same problem appears at 3500 rpm. It's also impossible to go over 4000 rpm.
All the sparks are clean. The motor starts good. The airfilter is clean.
What do you think could be the problem ?
I would be gratefull if somebody could help me
Don't worry if my "English" seems strange...but I am a non native speaker...
