1997 Toyota Camry 6 cyl Front Wheel Drive Automatic 216000 miles
I purchased my 97 Camry 1 year ago with 203,000 miles on it, and now have 216,000 miles. I had quite abit of work done at the time, including a tune-up. The car has surged while driving ever since I got it, but has become more noticible recently. I feel it most around 5 mph under light acceleration and also around 35-40 mph (right after auto tranny shifts into the next gear; i.E rpms drop). Under hard acceleration the car feels smooth. Occasionally the car won't idle (will stall). About 6 months ago the Check Engine Light would go on for 2-3 days, then go off. It seemed like the light would come on during high humidity days. This cycle repeated for a couple months, during which the following codes were pulled at the local auto parts store (P1410, P1411). I looked these up, and they seemed to point towards EGR Position Sensor. About 6 weeks ago the light came on, but didn't go off. I took it to the Toyota dealer, and they said there is a " misfire" problem (they didn't tell me the code number). They recommended replacing the ignition coils and spark plug wires. In reading your section " Car surges while driving", you mentioned that both sensors and coils (among other things) can cause surging. I was thinking of changing the EGR Position Sensor first (as it's the cheapest) and see what happens. Then change the coils/wire set. Do you think these could fix my surging problem? Also the local parts store has an " Airtex" brand sensor and coils. Is this a reliable brand?
