1990 Suzuki Vitara

Engine Performance problem
1990 Suzuki Vitara Manual

Hi, This does not happen all the time, but the car starts fine, if a little high but being an H reg im not surprised by this, I can drive for about 10 minutes and sometimes when I start to slow down the engine gets a litltle jumpy, and whent the acceleator is pressed down there is very little power. I have to put the clutch down to stop it from stalling. On the last few occasions however the car has stalled and takes a few times to restart and even then will not run for long. The car feels like it needs a cought to clear the system. I have used the injector/radion cleaner and I am unsure if this help and I did this 1 week ago and had the problem again.
