Zero power…bocks and jerks…ford escort BJ 1994 1.4l

moin zusammen;-)))) i have a ford escort tournament BJ 1994 1.4 with 71 hp and my treasure has been running better, because since 2 weeks it is jogging and bucking, no matter whether cold or warm…in between it goes out and then it goes some way. end velocities are on highway 140 with ach and krach…in the 5th it brings pure nothing more. gas hardly goes…as if you would step into the empty…it takes about 2 seconds until the car reacts…then it also goes out. my question, since I to p-laie bin… brings a diagnosis or what from the boschdienst? I would have had an appointment on Wednesday morning… then probably the necessary repair…is that worth everything? TÜV/AU 02/10…vehicle is dry and hardly rusty, very well maintained! New are air filters, ignition candles and vacuum hoses are tested by workshop. air filter box is dry: no oil! I would regret having to give it up. THANK YOU for a lot of help!
