I am a new owner of Mazda 626, 1.8 petrol,1996. Please help me in 2 problems, which may be related:
1) When I press the acceleration more strongly (ex, overtaking) it seems like someone's throat, it doesn't accelerate, it doesn't pull and it feels interruptions. If I lift the foot off the pedal and push it easier it will recover.
2) While running, if I switch to neutral, the engine speed ranges from 1500-500-1200-700-1500 rpm and so on. When I stopped the car the engine speed at idle remains fixed at 1400 rpm.
Where do I start from?
I apologize for any translation errors (google translate).
