1994, mx-3, 1.6 DOHC, atx. Idle issue, have no codes. Did wires, plugs, cap, cleaned butterfly, adjusted tps, cleaned air flo senser elements (had code 8 and 10 now gone). did air filter, fuel filter, checked timing. Did pcv, checked for leaks with carb clean. cleaned battery tetminals
Symptoms.....driving up to lights, hit breaks and come to complete stop...idles nice (around 900) then two or three seconds later idle drops suddenly ( to 7-750) and gets choppy.

with no codes, what would it be? The infamous cracks in the flex part of the intake hose.
![Question :?:](./images/smilies/icon_question.gif)
would that cause the exact symptom?
Has new alt, timing belt and water pump....
![Question :?:](./images/smilies/icon_question.gif)
would that exact symptom be caused by body grounds, or by air line to booster? i don't want to put any more money into this thing.

transaxle shifts hard when you put it into reverse or drive...could the mounts be bad? some one said there was a tsb about it but I couldnt find it. Somtimes it shifts hard when driving, 1st 2nd shift mostly (under medium acc) Did service (fluid and filter) made gauge and checked line pressure...was low, about 65. Brought it back up to 74psi but just shifts harder. No codes there either.
This is my first post so please be nice, lol. I have spent like 10 hours on here so far. Thanks for all the good info.
