Wanted to thank Scotty for answering my question live and yes it has helped a lot, again when i get the money banked up i will probably have to buy OEM Exhaust Manifolds from Toyota...yes there expensive thats why i tried to get the non-oem's off ebay but whoever made these things didnt smooth the interface down to match the engine block..I am going to ask a good mechanic if they can try to remold these ones and use them...im done messing around with them...But ironically this was not the only problem i was having with the engine...When i run the AC compressor its shorting out the electrical system causeing the ignition coils to misfire..ive already lost 1 coil pack due to this, and the Toyota good OEM ones are $100 bucks each..so everntually i'll replace all of them after the compressor has been swapped out..I also replaced ALL the vaccum valves since none of them were working and now have air flow in the vaccum...i was getting a failed vaccum test on the purge test step on your computer thing..my case the harbor frieght ZR15.....I got all the pipe leaks fixed when i used the sensor safe copper silcone gasket maker on the donut rings to hold them in place and create a good seal when i tightened the bolts..I also upgraded the bolts to more heavy duty ones, with a lock washer....
i still get a bit of slippage in the transmission on gear 3 but this has been a problem since i bought the vehicle...it tends to get better when you add or subtract transmission fluid or add trans X...but im going back to the orginal Toyota IV transmission fluid since this transmission is VERY FUSSY as to how much is in it and the fluid type with additives...I changed the filter and gakset and that helped a lot at first but i get the feeling the transmission does not like the Universal fluid so im trying the toyota one....
The car is running very smooth now that i put new vaccum lines on and put new basket filters in the fuel injectors...but get nasty hesitation when running the ac compressor so im assuming its shorting out the ignition coils...
one week at a time eventially ill have a new car
thnx for the input
ohh i also had to flush in the intake valves with CRC intake valve and turbo cleaner, while the engine is running because there is a lot of crude built up on the valves and i belive they were getting stuck? will have a mechanic put new valvles in and adjust the clearances in the future...

Uhh ohh I messed up lol…..I put too much Freon in the compressor and the oil went dry from vaping all the time…..I put a can of peg in and lowered the low pressure significantly…this has seemed to stop the compressor from interfering with the engine…
I’d say the car is almost running 100% now,,,,the valve cleaner really helped unclog the sticky valves this could have been the whole problem,,since the leaky manifold was throwing the o2 sensor WAY OFF…
Well more often if it hesitates with the AC on it's the AC compressor either straining the engine too much or a week alternator and or battery which can be tested
