Hi All,

I'm a newbie coming for help. Thanks!

My car is 93 accord 4dr EX automatic, with 220000km on it.

Thegas tank is leaking and my mechanic suggested filling only half tank every time. It works - No more leak from the tank.

However, I found the engine was cut off easily at any stops, no check engine light on. When I press the brake paddle, I could see the idle speed went very low and died sometimes - not if I approach the stop slowly. This happened only when my gas in tank was low to about 1/4 or less. Once I re-filled the tank to half full (couldn't be more because of the leaking), everything was fine: the engine was powerful, and idled smoothly at arround 700+.

I guess the engine was cut off due to low fuel pressure at idle, but I don't know how it related to a leaking tank.

My questions are:
1. Could the problem be solved if I fix the leaking tank?
2. Is it possible that my fuel pump is too old and needs to dip deeper in gas to keel cool?
3. Could it be malfunction of a pressure sensor? (fuel tank pressure sensor?)

Here is a list of what have been done to the car recently, after the problem happened:
a. replaced fuel filter (new)
b. replaced fuel pressure regulator (used)
c. replaced IACV (used, cleaned)
d. replaced PCV (new)
e. cleaned FITV
f. cleaned butter fly (from outside, not the whole throttle body)
g. re-soldered all solder joints on main relay
h. cleaned EGR valve
i. cleaned EGR ports (cleaned 4 only)

I've ordered a front engine mount (I thought it could be a high torque from my broken engine mount caused engine overload at idle), and I'm planning to remove and clean the throttle body (to improve idle). However, I do feel it's a fuel tank related issue.
It can't be the transmission. Engine stalls at neutral as well. It can't be a leaking brake booster - because everything is OK when fuel tank is half full.

I appreciate any of your response!

Thanks!

I am currently having the same problem with a 94 accord

 

i think its your fuel pump going bad..

 

Was there any resolution to this? I have the same symptoms, my fuel tank is in great shape however. 91 accord, exact same thing, engine rpm's drop or stall altogether. I swapped out the distributor because the main bearing of the old one was leaking oil through anyways... no change, exept a slightly better initial idle. Now I unplugged the IACV, resetting car computer with the TB screw slightly opened up more... see if this assist. Please help if you have any ideas.
