1992 Toyota Camry ENGINE SLUGGISH

Check that the air flow meter is ok, this should still be a flap type built into the lid of the air cleaner box.

I will check ,but I think there is not a flapper type on this car.it Is a 4 cyl..I think there is a air intake temp sensor in the air cleaner and then maybe a mass air flow sensor. I will check and let you know.

OK I will look a bit further into it as well

sorry for a late reply. i looked and did not see an air flow meter on the air cleaner box at all. what else do you think i should do? still the same and no check engine lights are on. could it be a fuel pump problem?

Run a scan anyway, not all faults set a check light, make sure that there are no codes logged first.

Ok once I scan for stored codes I will post a reply thanks.yesterday from a stop at a stop light once I gave it some gas the car response delayed slightly from a dead stop as if rhe gas pedal did nothing.like a dead spot.I will check the codes and post a reply. Thanks for responding

may be a throttle position sensor fault.

I just went to go look for codes but I have a problem, I have an OBDII code reader and my camry is a 1992, and all i find under the drivers steering column is a "DIAGNOSTIC" port which is grey in color and is round in shape. I am not sure how to read the codes on this 1992 year model camry. Can you help me ? Thanks

Camry here have a OBD11 connector under the bonnet on the L/H side at the fire wall, (that is on a R/H drive car) you need an adaptor from the Toyota plug to suit your scanner.

I HAVE TWO DIAGNOSTIC CONNECTORS. ONE UNDER THE HOOD ON THE PASSENGER SIDE AND I STILL HAVE THE ONE UNDER THE STEERING COLUMN ON THE DRIVER SIDE. THIS IS A CAR USED IN THE UNITED STATES.

When loading car info into the scanner it will advise on what port to use.

you may have not realized i do not have a scanner. i only have a OBDII scanner. NOT an OBDI. I went online and saw a video how to retrive codes using a jumper wire to jumper pin TE1 to E1 on the diagnostic port under the hood on the side opposite the cars battery. I will try it and let you know. the check engine light is supposed to flash and then you count the flashes in between the pauses to determine the # of the code. I will try this then post a reply. Remember I dont have a check engine light on so welll see.

OK, but not all fault codes will set a check light, that is why you should always scan or do a flash code.

ok i jumpered TE1 to E1 on the diagnostic connector as I read in a haynes manual. I got a code #f 21 by watching the check engine light flash on the instrument panel.This is the code for the oxygen sensor circuit or oxygen sensor heater failure. the oxygen sensor on my car is a single wire type. what do you think i can do before i just replace the oxygen sensor? any way to test the wiring if it has a braek or something? what do you recommend to do?

Fit a new sensor.

ok i will install a new sensor and let you know. just wait until i reply again.thanks.

Did you fix the problem?

I HAVE NOT HAD A CHANCE TO CHANGE THE O2 SENSOR BECAUSE I JUST BOUGHT IT ONLINE AND I JUST RECEIVED THE PART THE OTHER DAY. I BOUGHT A NICE DENSO O2 SENSOR.I BEEN WAITING FOR A DAY WHEN I CAN CHANGE IT WHILE THE ENGINE IS COLD. I USE THE CAR FOR WORK. I WILL CHANGE IT SOON. I DO WANT TO TELL YOU THAT THE OTHER DAY WHEN I WAS DRIVING I NOTICED THE CHECK ENGINE LIGHT CAME ON FOR A FEW SECONDS AND THEN WENT OUT WHILE I WAS DRIVING AND NEVER CAME BACK ON. SO THAT SHOULD TELL US SOMETHING. I NEVER CHECKED FOR MORE CODES YET BUT I WILL CHECK FOR MORE CODES BEFORE I CHANGE THE O2 SENSOR. THANKS FOR ASKING AND WAITING FOR MY RESPONSE. PLEASE WAIT.. I WILL REPLY BACK THIS WEEK.

ok, thanks........

I PUT A NEW O2 SENSOR IN YESTERDAY. IT WAS EASY TO PUT IN . I CHECKED FOR CODES AGAIN BEFORE I CHANGED IT AND IT ONLY STILL HAD THE CODE 21 FOR THE O2 SENSOR. SO, I DISCONNECTED THE BATTERY, CHANGED THE O2 SENSOR AND RE CONNECTED THE BATTERY. I DID DRIVE IT A LITTLE AND IT SEEMS TO BE RUNNING SMOOTHER. i WILL DRIVE IT TODAY AND SEE HOW IT RUNS. I NEVER CHECKED FOR ANYMORE CODES YET. I WILL DRIVE IT ALL DAY TODAY AND REPLY BACK ON HOW IT RUNS,

Just make sure all codes are cleared first so if a code is set, you know it is a new one.

I DID. I JUMPERED THE TWO PINS ON THE DIAGNOSTIC CONNECTOR AND MY CHECK ENGINE LIGHT WAS JUST BLINKING ONCE REPEATEDLY. I THINK THAT MEANS THERE ARE NO CODES. ANYWAY, THE CODE 21 WAS ERASED. I WILL CHECK FOR ANY NEW CODES TOMORROW.

sounds good, post only if you need further assistance with this problem
