Searched-Rough Idle after 1st start up
I bought this RX7 for 1200 .Owner claimed is was a bad fuel pump. I replaced the fuel pump, sock and cleaned the lines with an fuel system cleaner. I also cleaned the plugs and it started right up. But its idling like this and every time I put it in D (Its Auto) it dies.
Here's a video
I didn't replace the fuel filter since its on order
I think it might be a vacuum leak or the fuel filter.
Thanks

Vacuum Leaks, TPS, Timing
Make sure to start the vacuum leak check with the intake side of the throttle body, while you're at it make sure the AFM moves smoothly and is free of debris. I recently had a S5 vert brought to me that was running this bad and the culprit was a chestnut shell holding the AFM at max.

if i had a nickel for everytime i saw someone selling an FC with a bad engine that claimed "all it needs is a new fuel pump" i'd have a few bucks, but a few free bucks is still a few free bucks.
were the numbers 3 consecutive of that reading or did you just do a peak and hold test, like a piston engine?
a rotary compression test would be as follows:
F 110/108/110
R 105/108/106
which you can't do with a peak/hold test.

Ok I see.thank you.
If your looking into the engine bay, from the front of the car, the vacuum port closest to you, goes to solenoid or cylinder looking thing right?
Do I just spray a few hits of carb cleaner while the engine in running?
Thanks for your help so far.

I've heard that one plenty of times.
Sounds like the numbers are too low. If it was a 5 speed car with low compression, you could milk it by for a while, but the auto puts too much load on engine at idle.
