88 RX7 GXL
Start fine, no problem.
Checked my Idle, its at 790 when fully warmed up.

Only that the engine cuts out between 1500-2500 RPMs. When I try to keep is at 2000 RPM it pulsates. But if I give it more gas it will stay perfect at 3000 and up.
This happens in Neutral and when driving on the road. WTF!! Please help.

Does anybody know why this is happening?

 

i have the same problem man, im just rebuilding the engine, lol. i had the problem ever since i installed my rtek and 720's. ::shrugs:: no one seemed to know what it is becuase the diagnosis isnt for the regular hesitation problem so...

 

Just installed my Atkins Rotary Engine, not even 800 miles on it.

My problem started two days ago.
What part or sensor will cause the fuel to cut out or retard ignition(Spark)??

There has to be somebody out there with a solution. Please help.

 

search your *** off is all i can say right now

 

I'm thinking a dead spot in the TPS.

Try getting an analog multi meter (needle type, no clue if that's what they're really called) and test it. I find those better for finding dead spots because the needle will move. It's easy to miss a dead spot with a DMM. Just my opinion.

 

now, you mean piggy back the ecu and check while its running?

 

I'll try to see if my TPS is bad, Thanks.
