'87 Camry (Scooter) running rough...

Hey all,

My '87 4 cyl 24 valve 106K (Scooter) is acting up. In the mornings when first started, the engine coughs, spits and sputters until I hit the accelerator. Then all is fine. This eveing after pulling a small trailer, when I would try to take off, Scooter would try to accellerate but sounded like heave spark knocking until higher RPM's then ran fine. Also, when idling, the car will idle fine the idle will decrease almost like it wants to die the idles fine for about 10 seconds then repeats.

This just recently began happening. Have been getting a little spark knowcking shile driving but not too bad. Not like a bad converter. Possibile a bad TPS?

Appreciate any help,

DJ

hey I have the same problem with my 85 camry I have heard about a few causes.
(bad spark plugs, spark plug wires, worn dist cap & rotor, )
some cars it was the fuel pump and or filter that needed to be replaced.
although a fuel pump is quite expensive
but you should try putting some fuel tank additive/cleaner (for the fuel pump/injectors) in your gas tank along with higher octane gas-for cleaning the fuel pump & injectors, because they can get a sludge build up restricting the flow of gas. take it for a good run on the freeway letting it drive @ higher rpms for short bits to really get the cleaner to the pump and injectors. (this has cured some ppls problems)
try reaserching seafoam cleaner in the general camry discusion forum

I have also heard that it could be sludge build up in the throttle body, the solution is throttle body cleaner you can pick up at almost any automotive store....throttle body is located inside right after the air intake hose attaches to the EFI


finnaly it could also be carbon build up on the valves, and valve guides in the engine... which restricts them from either opening or closing causing misfiring, bad acceleration, and eventually stalling, to cure this they need to be replaced or cleaned, an expensive job also.

i havent gotten to this step yet.. right now I am checking the fuel pressure to see if it is my fuel pump
