ON: feels like hesitation when I accelerate, the lights dim when I shift, plus ign

Hey

I want to start off by saying this is the 5th G2Integra I have bought. It’s a 1992 Integra GS-R.

The B17A engine has been replaced with a B16A. The ECU is P61.

First, theres a hesitation when I accelerate - not huge, but it’s definitely there.

Secondly, the headlights will dim when I up/down shift (occasionally)

Third, the car will not start some times. Mostly on warm days (as per the previous owner)

The coil has been replaced (again, as per the previous owner)
I haven’t had the alternator checked yet, but I going to plan a day with a mechanic who repairs alternators and starters. Hopefully it’s a simple fix.

Anyway, if anyone has an idea, please let me know!

What do you mean , “will not start” it cranks but will not fire, or will not crank? 94
