Good morning and happy Saturday.

I bought a low mile rebuilt 2.0l engine that has carbs but also came with a full FI set up up that supposed worked fine before someone got an overdose of testosterone and felt the urge to tweak the fuel system (prior owners description (IMG:style_emoticons/default/evilgrin.gif) ).

Anyone put FI back on a car? Seems fairly straight forward but....

The cams with higher lift and longer duration and overlap create irregular intake vacuum.
The FI does not handle the vacuum pulses and irregular air flow very well.
A mild carb cam you may just get poor idle quality and poor low rpm drivability.
The more radical the cam the worse the FI handles it.

Personally I would probably take the chance since the process is reversible.
I might take the time to measure the cam lift, duration and timing.

Good luck
Jim

You can measure both duration and lift with the cam in the engine. It will take some measuring...effort....and math.

It can be done.
