I have just had the car fully serviced. Have yet to try the codes. Thankyou for the answers would like some more thoughts on the subject

Have had car to transmission shop and apparently it has a sticky valve in gearbox.
Thankyou for all your sugestions

Answer 1

In the automatic transmission there is avavle body . This has many chambers . looking like a maze of channels. When shifting the channels have transmission fluid flowing through them. There are check balls and springs in the system . if a spring or ball gets stuck with debree or burnt fluid it will stick.

There are some cleaners that transmission shops can flush through the system under high pressure. Often though the valve body will need removal inspection and cleaning.To prevent future problems change the trans filter every 7.5k -15 k miles , keep plenty of trans fluid in the trans as well as a complete trans fliud change evry 30k miles.

Answer 2

It isn't the transmission. If the transmission fails it will reduce the load on the engine, not increase the load. It is most likely an ignition problem (how long since the last tune up?) or a fuel delivery problem. If it has been a long time since the last tune up I would start with that and if the problem persist I would pull the engine codes. I would highly recommend changing the transmission fluid and filter to get whatever it was your mechanic put in there, out (at least most of it out). If he actually put something in there to help it slip, it will probably fail before long. Another thing I would recommend is not going back to the same mechanic.

Answer 3

i disagree that it would have anything to do with the transmission. If your stalling at lights and in reverse, its more then likely you have a faulty iac controller, or/and a dirty throttle body, that is causing the throttle plate to stick.
Pop off the air intake, and look in the throttlebody. If its black and has a carbon buildup, you can pretty much count on it being the problem.
You also should pull the fault codes.
I dont know if you know how to do this, or even what they are, so if you do, just ignore the rest of this message.
Under the passenger kick plate, there is a blue diagnostics port connected to two wires. connect the two ports with a paper clip end in each one, then turn your car to "acc", dont start it, the check engine light will flash, and then you can determine if the iac is faulty. count the number of flashes and number of pauses.

Answer 4

Throttle body needs cleaned. Get a can of spray cleaner in a parts store. {About $6.00} The throttle body sets on top of the intake manifld. It looks like a thin metal plate and is hinged witha simple pivot rod. It gets gummed up with **** sometimes and has to be cleaned. Follow the directions on the can . This stuff is non-flamable so you have to have someone revving up the engine while the other perso sprays the cleaner on the plate and pivot points otherwise your engine will stall out. If it does-no big deal. Other possibility is that you have a partially clogged fuel filter lor idle adjustment is too low.

Answer 5

Try the O2 sensor. It is notorious for stalling at stoplights. It could also be the EGR valve. These are both part of the emmision system, along with the fuel filters, etc.
I recommend you always start with the least expensive part in question first.
I would however, suggest you pull the codes first, as this is truly the least expensive way to go. It is also the reason the codes are available to begin with.
Good luck to you.

Answer 6

would first check that carb float isnt flooded eg small hole that allows the float to fill therefore lets fuel flow when not required hence flooding = stall at low revs had this problem a few yrs back took awhile to figure is easy fix install carb kit unlikly to be o2 sensors as these will not couse the problem you describe. could possibly be faulty stall converter good luck suggest take to honda specialist they are cheapest option in long run. if has catalictic converter remove and throw away they are useless and cause more problems than they solve your car will perform better without it

Answer 7

Get a sparkling sparkling bottle and take a gasoline pattern to ascertain for rust and water.the filler tubes can get rusty out and in causing water to come back in by potential of the wheel nicely,i'm In MI and it really is a complication-free situation on many automobiles.once you've water on your gasoline gadget tis ought to all acceptable be the area.the answer may be replacing the filler tube.i wager possibly the overflow tube ought to rust closed to causing extra back stress,yet now to not certain on that one.its ez to ascertain s no damage if i'm incorrect

Answer 8

Buy a newer car, its 16 years old, i imagine it has an insane amount of miles, honda's do last a long time but they were not intended to go THAT long

Answer 9

Buy a new car.
