To get started, you need a spark plug socket and ratchet and extension, plus compression gage at Sears $30.00 dollars. Check My Carspace.
#80 of 98 update on stalling problem by hannabanana Oct 07, 2008 (4:02 pm)
I had my brother help me look at the car. We couldn't find any vacuum leaks. He did an old fashioned test of putting a little bit of gas in the air filter to see if the car is getting fuel. Sure enough, the car ran fine until it burned out the gas, and then it stalled. He thought that was a sure sign of a fuel pump problem. We replaced the fuel pump, and it did not fix the problem. It did not seem like there was much or any fuel pressure in the lines. Is there a way to check the pressure in the line? Is it possibly some air flow issue still, even given the fact that it keeps running with gas poured in the air ducts (which seems like fuel delivery to me)? What about EGR or iac valves or mas airflow sensor? These parts are expensive--is there any way to test them? the car is throwing a code, but I don't want to spring a hundred and fifty bucks for the reader unless it will tell me exactly what is going on.

yes, the fuel pump turns on (I can hear it), so it's not the fuse or electrical. Now, I don't know if the pump is actually pumping or if the fuel filter is allowing fuel to get pumped. Replies to this message: rearwheeldrive (Oct 10, 2008 1:13 pm)

Replying to: hannabanana (Oct 07, 2008 6:32 pm) If the air duct from the air filter has a crack, it screws up the mass air flow sensor readings and runs poorly.    I'd remove it and look under it for a crack along a seam on one of the ribs. A squeeze test of this duct while running, will cause it to stall out.    Dont buy a Mass Air Sensor till your sure it is bad. I bet if you disconnect the Mass Air Flow sensor it will still run. Some cars computers go into default and will still run on the default settings if it senses a malfunction in the Mass Air Flow Sensor.
#84 of 98 MPG on a 2007 V6 XLE Camry by djm2 Oct 17, 2008 (4:01 am)
Good Morning All:          I just returned from a road trip to New York State. I traveled at 70mph on the NYSTW, and the vehicle got 31mpg! ---- This was achieved on 87 off-brand fuel. ---This is OUTSTANDING for a V6 engine.          On entering the highway from a rest stop, I accelerated "hard" to see how this vehicle would perform. Within seconds it reached 80mph! ----- The shifts were smooth and positive. (The vehicle peformed like a "ROCKET"!) This vehicle could easily cruise at 100mph! (I would love to try this for about 1/2 hour somewhere if "RADAR" was not an issue !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!)--------- It is truly a road car! --- (Life was more fun years ago without road radar.)         Best regards! ------------------- Dwayne

I have a 1997 toy camry with 256K on it. It is a 4cyl. It will start and run great, however when you give it gas it chugs and close to stalling. When you give it gas slowly it will not chug, well just not as much. When you give it gas it is very slugish. check eng light came on. Could this be a trans or fule system problem? What could be doing this? Replies to this message: kiawah (Aug 23, 2009 1:01 pm) clindstrom (Aug 30, 2009 11:57 am) kiawah (Aug 30, 2009 12:07 pm) wwest (Aug 23, 2009 2:06 pm)

Replying to: clindstrom (Aug 23, 2009 12:47 pm) Could be any number of things. Take it somewhere and have the computer read, which will give you the error code. That error code will tell you the area that is causing the problem. Many autoparts chains will read the error free of charge for you, and suggest what the parts are to fix the problem.

Replying to: clindstrom (Aug 23, 2009 12:47 pm) ...256K........   Burned/leaking intake valves.   Combusted gasses only leak back into the intake manifold and ignite the gas there (stumble..) with HIGH cylinder charge volume.
#88 of 98 2007 Camry XLE V6 Air Flow Sensors, Manifold by skoman1 Aug 30, 2009 (9:46 am)
Help... Took my Camry in after the check engine light came on, dealer stated "need to replace right side air flow sensors and the manifold" based on the codes extrated... $1500.00. Car has 68,000 miles on it and runs like a top. Service manager states the air flow sensors are measuring the air and fuel mixture incorrectly (to lean).   Anybody heard of this? Can't find any info on this.... Help. Replies to this message: kiawah (Aug 30, 2009 10:59 am) skoman1 (Sep 03, 2009 7:49 am) kiawah (Sep 03, 2009 9:30 am)
