i have 95 auto maxima...after it start up..the engine tachometer seems to jump up and down a bit...feels like it might stall but never did...recently it got worse....if i drive off the engine shake really hard and you can really feel though the whole car...like it would stalls bad...car a little jerky too...dont know what it is...i think it goes away when engine is warm up after a few min...has a check engine light...went to autozone before but i ignored it....any helps
