3rd & 4th Generation (1992–1996 & 1997–2001)Toyota Camry Discussion for years: 1992-1996 & 1997-2001
Topics of discussion range from fuel economy, safety, modifications, performance all involving America's favorite family car, the Toyota Camry.
Hi guys. Just did a load of work on the car.92' 2.2 L 93000 miles. Did strut assembly all around, new brakes,exhaust,plugs,wires, flushed radiator new air intake,cap ,rotor, fixed leak in oil cooler, and cleaned engine compartment. Now the car is bogging down off a dead start. Also rough idle almost stalling at a stop. Once it gets going car runs like a top. Cant figure out what it is. Read some threads and cleaned the throttle body and checked everything. Also added some fuel injector cleaner. seems like maybe not getting enough fuel not be sure. NEED HELP
Is the bogging down with the engine warm or cold? What did you do on your exhaust work? Are you sure you got your vacuum hoses back on correctly? Check for leaks/cracks in your intake hose. What do you mean by 'new air intake'?
Car is bogging down hot or cold. I am in the process of checking for a vac leak. I took off the old box air filter and put in a spectrum with the. sensor. I did that first and had no problems.Strangely enough the last two things I did seems like it started my problem .. I did the wires , cap and rotor and flushed my radiator. I really feel like its something with the flush I did. The coolant came out like chocolate milk.I didnt drain it from the block. Now wish I did. I checked the hoses for collapse...... nothing. I emptied the radiator and the overflow. Been at it all day, cant figure it out. No engine light so i have no codes yet...................I just had the wife rev it up to a grand so I can see what is going on and it stalled ,and smoked out of my intake? I was after I cleaned out the t/b. I was better off not doing anything to it...
I doubt the coolant has anything to do with your issue if it started after your work. However, brown coolant is never good and can indicate a oil. You really should do a full system flush by removing the top rad hose and feeding fresh water (distilled if you chose) into your rad until you get clear water from the engine. Then add your required fresh coolant concentrate to the rad until done, stop the engine and reattach the hose.
What plugs and wires did you use?
I would remove your new intake stuff temporarily and put back the old to see if it cures the problem.
Smoke from your intake would indicate possible burning off of whatever you used to clean the intake and TB? What exactly did you use? As well, don't know why you would have smoke coming out of the intake since it is usually sucking air into the engine, no? I assume this is at idle?
Check your egr valve to see if it's plugged. Are you using the right spark plugs? I've heard a lot of gen 3 camrys use the dual electrode spark plugs to run correctly but not certain.
it does sound like either an EGR or dirty throttle body issue being that it goes away as the engine warms up. i would take apart the throttlebody and clean that first - cheap and easy to do. if that doesnt fix it, check the EGR for blocked lines.
I used NGK plugs. I did the plugs a few days ago and all was fine. I later did the cap ,rotor and plugs. Used t/b cleaner that is safe for all sensors and cats.As far as the intake ,I went back and put the old one back on. That didnt help.I had the new intake on for a few days and all was fine also. I went back and checked my plugs( gap and color ), all fine. I believe also that the problem is in my t/b or egr. I will check more in the morning. I cant believe I spent all day on this and got nowhere. I also disconnected my fuel pump. Will change that in the morning also.(just to eliminate) . just to clarify the problem doesnt go away when car is warm or cold. Car runs fine after takeoff, runs great . I have a block where I have to jump into traffic and when I go to give it gas from a stop I bogg down. Didnt have that problem till I changed parts. Didnt have this until I flushed rad and did the cap rotor and plugs and cleaned t/b. As far as the egr how can I check if its the problem? Also I am not setting off any codes. I think the smoke in the intake is also from the cleaner. I thought the rad flush might have clogged a hose or something ,but dont know. Will reflush again if I have to pull off the t/b.Thanks all 4 your help.
Actually, maybe it is related to your rad flush. Maybe the Engine Temp Sensor is not sensing engine temp properly because of a trapped air bubble in the coolant? ie. not topped up properly? It's possible that could cause problems. But then you would think that it would only affect the engine either cold or hot though.
To check your EGR, you can pull the vacuum line off it and give it a few taps with a wrench or something to make sure the valve is seated closed ok in case it is sticky. Then drive it like that to see if it makes a difference.
Your IAC valve may be gummed up somewhat from your attempted cleaning, or maybe the connector going to it is not seated properly? Or maybe you fried it entirely? To get it to idle better, you can try to open the throttle plate manually a tiny bit to see if idle improves. If it does, then it is likely your IAC. You didn't play with the throttle stop setting or TPS did you?
Another possibility is the MAF sensor not working properly and sensing low vacuum when accelerating from a stop with the TB plate open. This would prevent the ECU from increasing the injector open time initially I would imagine.
I would check fuel pressure with a gauge at the filter first before replacing the fuel pump. That's a lot of work, no?
I assume you did not attempt to adjust engine timing by loosening the distributor itself? Ie. you just removed the cap and rotor, right?
yes,just replaced cap and rotor. I didnt know you could adjust timing that way.I AM GOING TO FOCUS ON THE SENSOR AND VAC LEAKS TODAY. I will check for air bubble in rad, but after initial flush i gave the hose a squeeze to clear air bubbles.To remove t/b I think I need to drain rad so I will eliminate that problem today . I was told this could be so many different things . Cant figure it out yet. TODAY IS ANOTHER DAY. i WOULD HATE TO HAVE TO BRING IT IN AND PAY SOMEONE AFTER ALL THE TIME i HAVE PUT IN.
sounds like the problem i had a month ago. i had the exact same symptoms... the culprit was a cracked hose at the tip, connecting from the left end of the throttle body to an electrical component mounted on the firewall. i opened my hood and listened very carefully while the car was running and just barely heard the leaking vacuum noise.
before discovering the vacuum leak, i had replaced the fuel filter also, which didnt help my problem.

you don't really have to. just plug the coolant hoses you disconnect with a cork or rubber plug. If they leak a little while you are working on it, no biggy.
You never mentioned what you did with the exhaust?
oem replacement. First thing I did two weeks ago,original one was gone. Car was fine after that. I think it might be a bad plug or a vac leak. I am still out there trying to figure this out. Thanks again. will check back soon for suggestions.
