Explain more in detail

 

it feels wierd like it has power then it loses power. its like after it gets over that surge it has more power.. it does it though all the gears. i was wondering if maybe it could be the timing at what is optimal timing??

I had a similar problem with my 86 Trans Am i have now.The problem wound up being my MAF sensor.Apparently the filiament wire inside was broken.Just my personal experience.

I am have the same problem with my 92 Z28. I know what is wrong with it, just haven't had time to fix it. Below 2500rpms is trash(like you have a larger cam in it or like a torque converter clutch in switching in and out). It is the distributor. The poll piece in it. I have seen a few act like that. it is the worst arouns 1400-1800rpms(light loads). under power it goes away.

 

could it also make my car act like it has a stall converter in it? cause today it was surging just the same as ever then it started acting as if maybe it has a stall and its stalled around 2000 rpm but then sometimes it doesnt act like its stalled so how much for the distribitr part that u were talking bout do i need a whole new distributor or just the pole piece thanks

When it surges, does the RPM go up or down? I know this sounds like a dumb question but it would help to know.

 

when it surges the rpms go up
