i swapped a jdm b20b and running into more problems.
mods done are: ES poly mount inserts, and a AEM SRI

1. when the car is warmed up, it will idle at about 500-600 and shakes the hell out of the steering wheel. but it will only do this when the car is warmed up, also it bogs so much a minivan could beat me off the line. and again only happens when the car is warmed up. when i did the swap i put 5 quarts of 10w30 synthetic in it, and it was a a little overfilled, so i just drained some tonight, and it didnt do anything. Also for the bogging, my exhaust piping broke from the hanger where the resonator bolts up to the pipe after the cat, so right now i have no exhaust from there back which im kind of leaning toward that as my bogging problem, for having no back pressure? lasty, the injectors have 300xxx miles on them, which are probably a little dirty, but what are some bigger obd1 injectors i can use?

2.the transmission kind of does the same thing, when its not warmed up it shifts smooth as butter, but when it warms up, it sticks in gear, and i gotta actually push it to get out of gear. shifting out of 2nd and out of 4th is the worst of all the gears,. but again, only when the car is up to operating temp. when i swapped the new motor in i got the honda manual tranny fluid from the dealer, and the dude there said it will take 3 quarts of fluid. Im pretty sure i drained all the fluid out when i swapped it but that could be overfilled too.

before i start wasting money by throwing parts at the thing, i wanna see if anyone had these problems before.

the car is a 95 ls, so its OBD1. What are tuning options for the p75 ecu?

1. Clean the throttle body and IAC. Bleed the coolant too. Honda's are picky about air bubbles in the cooling system. And lastly, most of the B-series throttle body's have an idle adjustment screw if you want to turn it up some. It should be noted though, Honda's, at least the older ones, ALWAYS had some steering wheel shake. The mounts would only make it worse. Also, check the condition of your timing belt and ignition timing. IIRC, the H22 injectors are around 345 CC,

2. Make sure you have the right amount of fluid in the transmission. It varies depending on which transmission you have. Also, polyurethane transmission shifter bushings are available and your car, and they make a big difference in shifter feel and accuracy.

I miss my Sunfire, I want it back!
MMMM, HIDs
You will be missed.

Ooops I skipped right over that part.

yeah its the stock ls ecu, i got hondata s300 ordered now, so now i gotta find someone to help me to tune it, after it starts running right. Im pretty sure its from a mixture of everything, my cat is clogged bad, from when i had a bad intake mani gasket and it was running real rich. plus i need new injectors. and lastly the no exhaust, with no backpressure, but i have a dc sports header, and my buddy has some 2.5" piping left from his crx, so im gonna make a test pipe, and full exhaust this week.

o yeah, and hopefully hit up the jy for some new injectors, anyone know what other OBD1 honda has bigger injectors with the same clips?

The only Honda injectors that will swap right in that are bigger are the h22 injectors. Anything else will either require modification, a resistor box, or both.

A resistor box is stupid easy to use. You shouldn't need bigger injectors at all unless you have different cams and or other heavy mods. H22's use 345cc's though.

well i was gonna pair them up with a walbro pump, and tune them down, until eventually when i can get a set of crowers
