Replying to: natekelly (Nov 16, 2008 7:06 am) Sounds like an ignition system issue. Have we had a tune up lately?

But your problem could be many things, you should take it somewhere to have them diagnose it properly. Replies to this message: Mr_Shiftright (Nov 17, 2008 8:50 am)

Replying to: kiawah (Nov 16, 2008 2:02 pm) Could be, but I'm always suspicious of ignition when the problems start at a specific rpm....seems to me if you had fuel pressure that bad you'd never get up to 2,500 rpm.
#4659 of 4962 Timing chains on Toyotas by inkie Nov 17, 2008 (10:12 pm)
It would be appreciated if anyone can let me know what Toyota models {if any] have steel timing chains? Also, do any engines they manufacture are non-interference? Thanks. Replies to this message: suvshopper4 (Nov 18, 2008 6:41 pm)

Replying to: inkie (Nov 17, 2008 10:12 pm) I know the 2.0L 4-cyl in the 2001 and forward RAV4 has a timing chain, not a belt. I have read that Toyota engines are non-interference (unlike Honda). -ss4

Thank You, I have not had too much luck with these questions at the dealers in the Lehigh Valley.Whenever I get there the service manager is not in and the underlings were probably told not to discuss anything and refer me to the service manager. Pretty fancy not like Honda and GM. Now that I have some engine models it may be easier to get specs.
#4662 of 4962 code 1810 by shooter7 Nov 20, 2008 (11:46 pm)
I have a 2000 saturn l series 300 v6 with transaxel. it wont go forward or reverse. code checker says 1810... ATF pressure manual valve position switch malfunction. can I fix this from under the car or does the tranny have to be taken apart? thanks Replies to this message: Mr_Shiftright (Nov 23, 2008 10:06 am) shooter7 (Nov 23, 2008 1:21 pm)
#4663 of 4962 Lexus ES300, 1994 front rotors 270K by edouble1 Nov 22, 2008 (6:28 pm)
Trying to replace the front rotors. Seems pretty straight forward: remove the wheel, remove the break calliper, remove the calliper bracket, slide the rotor off. I can't get the rotor off. I don't think they were ever replaced before, and there is 270K miles on it. What are the chances it's rusted on? Will PB blaster help in the process? How hard can I bang on the back of the rotor with a hammer, if I use a Hammer/block of wood, or a rubber mallet? Thanks for your help. Replies to this message: bolivar (Nov 23, 2008 1:45 am)

Replying to: edouble1 (Nov 22, 2008 6:28 pm) You can bang really hard. But at 270,000 miles????? If there are not separate bolts that hold the rotor on, the lug nuts hold both the wheel and rotor, here is an old shade tree mechanic trick that you might try. Put the thing back together. But leave all the lug nuts loose. I don't know how loose, maybe about one turn from being tight. Then just move the car back and forth a short distance. Maybe turning the wheel back and forth. This might break the rotor loose. Don't blame me if this strips nuts or shears them totally off. This is just a 'trick' I've read about, never actually done.

Replying to: shooter7 (Nov 20, 2008 11:46 pm) The Transaxle Fluid Pressure (TFP) switch assembly consists of six pressure switches. Five of the switches are normally open, and determine gear range selection. The sixth switch is normally closed, and detects Torque Converter Clutch (TCC) release fluid pressure. The TFP switch assembly also contains the Transmission Fluid Temperature (TFT) sensor. These components are combined into one unit, mounted on the valve body. The TCM provides ignition voltage on the three range signal circuits. By closing (thus grounding) one or more of the switches with fluid pressure from the manual shift valve, the TCM detects the selected gear range. When the transmission electrical connector is disconnected and the ignition switch is On, the ground potential for three range signals from the TCM will be removed, and an illegal gear will be indicated. (Refer to TFP Switch Assembly Logic Table.) DTC PARAMETERS DTC P1810 will set if: * The gear position indicated by the TFP switch assembly is illegal for 60 seconds . * Engine running. DIAGNOSTIC AIDS A pressure regulator problem could set DTC P1810. Inspect the wiring at the TCM, the transmission connector and the TFP Val. Position Sw. connector, and all other circuit connecting points for the following conditions: * A bent terminal * A backed out terminal * A damaged terminal * Poor terminal tension * A chafed wire * A broken wire inside the insulation * Moisture intrusion * Corrosion When diagnosing for an intermittent short or open condition, massage the wiring harness while watching the test equipment for a change.
