1995 Toyota Camry Repair Question
Check engine light 25,26, and 71.
You should not have tampered with the stop level screw. That is factory set for the throttle plate to be closed at a certain position. Adjusting it would affect idling and the TPS adjustment.
For idle adjustment, there is another screw on throttle body which is turned to allow more or less air to increase or decrease the idling speed.
Final ... My car run so smooth and great engine so even on highway... Last night, we go long trip on turnspike road , it was so really bad misfire long way trip about 2 hours drive for my family's ICU Hospital then we gone home very worse misfire alot at night time , so I pull out the spark's wire for check out ... I saw that spark shoot double at wrong place ... It was long tip of deep spark wire shape about 4 inch plastic plug , that how made of over head cam for deep hole spark plug, that crazy hard to see of where is misfire from ... Anyway, that I found a crazy burst of side so tiny hole from spark wire's plug of side plastic ... That hard part of trouble shooter, my god... So, I replace a new spark wire , car's engine run beautiful for now, thank you very much....
Yes, bad plug wires can cause a lot of problems and non OEM wires tends to shorten themselves as you push them into the plug tubes. I would recommend OEM plug wires whenever possible, even a used set is better then after market.
Hi guys, again. It bad news so far, that car was very good idle and drive speed very good but over 50-65 mph seem engine stumbles on acceleration at Turnspike Highway...
Have the fuel delivery system checked, maybe the fuel filter is clogged or the fuel pump is working below efficiency.
Okay, the fuel pump was change 4 year ago for long trip. It still higher pressure fuel gauge reading. It time to change the fuel filter for now.
Now, I believe the ECU not working propertly, because the check engine light code was show Code 41 problem. That I already follow the measure the adjust new TPS sensor with Ohmmeter reads infinity. So far, few hours drive and then stop at parking alot few minutes engine idle hot for awhile and then it feel like the engine's rpm show idle rough a little bit stall and then run normal , rough and normal three times then the engine back normal for light went on for "Intermittent" Codes... I wonder why of always read same Code 41 again. All TPS's connection plug and circuit look perfect work ... For now , what you think of ECM ???
no respond at yet?
Sorry, did not get your message as I had some problems with my internet service provider for a few weeks.
Intermittent codes can be due to the ECM or a loose wire cnnector somewhere.
