have u checked your fuse? a few years back i have some problem with my fuel pump, the symptom was when you accelerate past 1500 rpm it sputters and jumps but the idle is perfect. they say this symptom is the same as that of a busted airflow sensor. last year another problem occured but this time it is in reverse in idle its erratic and in low acceleration it sputters and jumps like a horse but pass 1500 it normalizes it turns out the problem was the high tension wire. i replaced it and solved the problem.

 

I did check all the fuses and they are all fine. What high tension wire are you talking about? Sorry... I know my way around cars fairly decent but am still learning and that is something I haven't heard of yet

 

high tension wire is the 4 wires that connects the spark plugs to the distributor. some call it the spark plug wires. current usual jumps out from them. this is how u test it if its working fine turn the engine on with the ac on remove one wire then insert a screw driver (remember that ur driver has sufficient insulation other wise u'll be electrified) when inserted place it near the metal surface of the engine do not mak contact make enough space to see the electricity jump from the screw driver ot he metal surface. now observe the spark if the spark is constant and regular the wire is fine if the spark is erratic then the wire is busted and needs replacement. repeat the same procedure to all the wires
