ok ill try and let u know the out come

 

Thanx for the help guys I found a fuel injector shooting gas so I changed all the injector seals it stopped leaking cleared codes and plug in my vtec car is running fine so far

 

95 accord ex vtec f22b1 4clynder automatic



so i bought this car in February thought i fixed the issues
i changed alot of stuff car runs good for a day or 2 then acts up like before
i changed vtec solenoid fuel injector seals egr valve tcm ecu distrbuter cap and rotter and main fuel relay and spark plugs fuel filter

all the problems usually occure depending on the levels of gas in the car and when in side of the car is really hot and i have been pulling codes
cel/15/21/12 and tcm/14

when the car usally gets hot gives hard time to starts will crank and start then rev up to 2grand then die out then if trying to start again it just crank crank crank but will not start if u wait little while then engine will usally do the same thing for about 2to3 times then starts up

the the othere issues is start the car in the morning rev the car it rev to 3 half then rev it again then gose to 4half then when car is warmed up will rev up to 5half and usally sounds like motor is bogging down like its starving for gas

then when first starting the car has no cel or tcm light flashing then when i start driving cel well come on and car starts runing rough and u can smell the fumes really strong and even sumtimes d4light even comes on and flash when that happens light black smoke comes out tail pipe and even driving regular with no cel or with cel on car sounds like its bogging down when i gas it to pick up speed and vtec will not engage and the fuel gage while in drive pushing gas pedal if on half tank will move up to 3quater tank the when i slow down it well go back down little below half tank the a few seconds will go back up to half tank.alson car swallows gas like it is thirsty like a human

hope some one can help me plz it would mean alot thanx hope i covered every detail so someone can help me if any questions plz leave them and ill get back asap

 

Since original post, you have changed the TCU & ECU w/ presumably used units? Please confirm.

I'm at work and will need to research to respond.

good luck

 

ecu got changed when my car was in the shop i believe its used as well and the tcu yes is used from a junk yard

 

the Mechanic was working on my car at the shop said he changed it with a second hand ecu

 

cel/15/21/12 and tcm/14

CEL 15 - Ignition out put signal, usually ignitor but coil/spark plug wires can also cause. Probably not source of your problems.

CEL 21 - Vtec solenoid valve. Suggest checking solenoid for function w/ application of 12V to wire. You should hear a click. If not solenoid is bad.

CEL 12 - EGR valve lift sensor. A problem that can wait. EGR generally does not cause drivability issues, only emissions issues.

TCM 14 - This code is very difficult to explain w/ a change of TCU/ECU unless you have a wiring fault in the brn/wht (FAS) wire between TCM/ECM. You will need to pull the connectors and check continuity of the Brn/Wit wire. Connectors D16 and A18 of harness.

good luck

 

All what u just said I have done vtec solenoid is good and the other stuffs I check is there anything else I could do
Do u think its electrical issue maybe

 

And I also for go to mention when I drive around the main fuel relay gets really hot

 

MFR's get hot. I measured high temps (120F? been some time) on bench setup after noticing how warm MFR was after testing.

Re Code 15, if vtec solenoid is good, then either wiring fault or ECU fault.

Check wire continuity w/ VOM from ECU connector to Vtec connector by grounding one end and checking for continuinty to ground at other end. Also check your wire into/out the vtec connector. This single wire gets a lot of abuse. Mine failed and I had to hard wire directly w/o a connector. In the end, I found the ECU was the real problem.

If wiring is good, the ECU is bad despite it's being replaced?.

Code 14, you need to check the brn/wht (FAS) wire between ECU and TCU. In this case both connectors can be accessed at same time, so simply do a continuity check for low/zero resistance on the brn/wht wire path.

good luck
