Hello,

It's my first post here,

I have acceleration problem in my Mustang, i have LPG installed but it happens on petrol also. When i need to accelerate quickly its choking/jerking on higher RPMS ~4000-5000. I already replaced Spark plugs, coil, cables, alternator, and cleaned throttle body. I saw that sometimes "Theft" wont turn off after engine starts but car drives normaly (maybe it's connected with acceleration problems). I red that it can be ECU problem, so i removed it today, and connected on table but because of lack of IC's datasheets its just waste of time to check voltages. Maybe anyone had similar problem?

I would suspect a faculty sendor such as mass air flow, throttle position, or cam position. Try unplugging one sensor at a time and take it for a drive.
