I have a 96 Gen I Mark with OBD2 and have a Davis Drive Right Chip that I just put on it for a long trip I took over the past weekend. This chip allows you to monitor up to 4 of about 27 different perimeters including things like engine speed, temp, intake pressure, TPS, O2 sensors and - engine load. I also have a acton 9145 scanner and just hooked it up because I got graphs that I couldn't believe after downloading the chip data-engine load on the Mark is like 30% at idle, goes up to 80 or 90% with light acceleration-on other cars I have, after warm-up, most show load readings around 5-8% at idle, and rarely do I see readings above 50-60%. I turned off all accesories like AC, it has no engine noises (water pump. pullies, alternator quiet)-I am wondering, does anyone know if this could be related to my trans?
I did the 1-2 shift accumulator change when I bought it back in September 06 and drained all the fluid including the torque converter, replaced with Mercon 5, but it still takes a long time to shift into 2ed. There are no codes, and it runs pretty good, is quick and gets decent gas mileage (16-17 around town, 23 highway. If I don't get on it from a stop, it shifts ok, but if I come off the line hard, I have to back off the throttle to get it to shift into second-torque converter? Any ideas? thanks
