94 accord EX f22b / vtec won't engage
i got a 94 accord ...automatic
i got the car from a guy that put the engine in after the last person locked up the engine.
i figure he put the orginal trans....cause after 6 months the filter stoped up and the car wouldn't move. i had a junk yard one put in and now the vtec tends to not engage.
basically when i drive it the C.E.L. comes on after it shifts....into second
i've look at a few topics but need more info....

i'm going to now cause i thought it was lack of oil but guess not....but it doesn't do it all the time...there be times when my vtec bangs hard and then when the light is on its seems to have a slower acc.

and what RPM did VTEC engages? There's only certain RPM on these motors. VTEC engagement on these are not like an H22.

its not a h22 it the sohc f22....2.2L/sline
i also just found out that i have an oil leak ...but its not my valve cover or anything like that....its on the left back side of the engine....

Re: 94 accord EX f22b / vtec won't engage
also your rite its more like a 3.5 rpms when it engages....
its werid not having v-tec(untill this morning ).....can a car run normal without putting more stress on the engine > running without vtec?

Re: 94 accord EX f22b / vtec won't engage
Yes, the last CEL that was on will be stored in the ECU. Some CEL I heard will prevent VTEC from engaging. Yes, a car can run w/o VTEC and still drives fine but you just won't feel it at all.
My H22 ran fine with no VTEC for almost two weeks because I mixed up the VTEC pressure switch with the thermostat sensor housing.

[QUOTE=The(704)kid;41104005]i also just found out that i have an oil leak ...but its not my valve cover or anything like that....its on the left back side of the engine....QUOTE]
is it coming from near a small cilinder that sticks up from around the back left corner of the valve cover? if so that sounds like the vtec control solenoid. there is an o-ring that can cause a leak. the o-ring is cheap like 4 bucks from the dealer (unfortunatly its a dealer specific, most shops wont have a clue what you are talking about.) i'll pull up the part number in a little while and try to find my pics of it

Re: 94 accord EX f22b / vtec won't engage

Re: 94 accord EX f22b / vtec won't engage
I have a 93 accord automatic with a 94 sohc vtec motor. The guy I bought it from said he put the trans from the 93 non vtec motor in it. He didnt change the computer for the engine or trans. The car shifts high and hard and doesnt go into 4th. Ant tips on what to do. change the trans, computers, selinoids etc. Thanks

Re: 94 accord EX f22b / vtec won't engage
Get an OBD1 P0A VTEC computer. That will help your shifts and it will engage VTEC as well. The stock 93 computer is non VTEC.
Check the FAQ for VTEC swaps into the 4th gen, CB7, 90-93 Accord and you will see that there are a couple wires that are also required to add VTEC.

Re: 94 accord EX f22b / vtec won't engage
Thanks for the input. Believe it or not my vtec does engage. I think he may have changed the ecu but not the tcu. Should i change the tcu and the silenoids and see if that works.
