I have a problem with my car at the moment, I'll try and describe it as best as possible.



At about 2300rpm, and always in the same spot, if I'm just driving along and slowly accelerating when it hits that spot its as if it just hits a wall and stops building revs unless I put my foot down harder.

It has a 2500 stall, which was rebuilt and the problem was there before I had it done.

Doesn't seem to do it when cold/just started up.

Any have any ideas of what may be the problem?

Thought it may have been a tuning problem but isn't,
have changed plugs and leads,
even new injectors

Mechanic changed over other things also but still there.

I have the car at home now and going to try and sort it out so any help appreciated.

not tune related your positive? maybe fuel related then be checking your fuel pressure and maybe replace regulater.

Oh another best to do it first new rotor button and dissy cap could defenitly be spark breaking down under load

It has to be running out of fuel at 2300, tune or otherwise

mates ed turbo did that at 2700rpm was dissy cap rotor button as it was the most load just as it came off the stall. Worth changing anyway if it hasnt been done yet'
