Sputt Sputter from thee ol camry

[WhippinCamry]

Hey everyone, i missed you guys. Very helpful people.

Ive got a question about my 91 camry dx.

let me inform u a little bit on what ive done.

short ram (custom) sealed off not leaking from what ive inspected about 15 times.
-new used distributor and $100 cap and wires from napas premium line.
-denso stock plugs and a set of ngk v powers
-tps sensor
-egr cleaned
-throttle body cleaned
-all new vaccum hoses.
-fresh oil
-tranny fluid is looking good
-timing is advanced 2-3 degrees
-throttle cables nice and firm and idles fairly smooth


Okay the problem is, i went to recharge my ac with r-134 a i beleive
to the lower port. and followed instructions on can.
dye sprayed out of the port on the rail.
it was a little loose but by the time i tightened it
it all seeped out and i still have no cold air.

car didnt sputter before this

i noticed when the ac was on the car almost died but still ran on a low idle. i upped the idle speed a tiny bit.
and now my car sputters on acceleration, doesnt feel like a misfire though. its almost like a smooth pulsating.
ive kept the ac off sence and it still is doing it.
checked all the basics and looks good to my eyes.
throwing NO CODES.

i have been about quater of a tank latley. so i put some iso stuff in it and it seems to help a little but is still doing it.

note; ive ran about 200 dollars worth of fuel injector cleaner sence ive got the car last summer.

alternator belt not tight enough? fuel pump? injectors?

car doesnt stumble unless its in drive or reverse.
THANKS A BUNCH!
