Fire from exhaust pipe now won't start what could be the problem
Engine-tranaxle disengaging happens at highway speeds, when gaining elevation or moving into a curve, for example. Seems to me to be at the final phase of automatic transmission shifting where lock-clutch would kick in. I am at highway speed, either on cruise control or accelerating slightly, when suddenly the engine-transaxle disengages, the engine rev's, I take my foot off the accelerator (if not in cruise control), the engine rev recedes, and engine-transaxle re-engage. It is happening with increasing frequency, most recently about 5 times in 2 hundred miles of travel.
Another symptom is that on occasion, when I am slowing the car to a stop or near stop, the engine starts to stall and "engine service" light blinks momentarily. Have read this could also be a torque converter lock-clutch problem.
What does this problem indicate to you?
If the lock-clutch or torque converter is the problem, can the torque converter be serviced at less expense and complication than the rebuilding or replacing the whole transaxle?
My shop mechanic (3 times) and dealer (1 time) both could not pick up the problem (no computer codes registered, and I sense they are unwilling to test ride 100 miles on the highway to try to experience the problem; my local mechanic drove it around for 24 hours). I am grateful that neither went on a wild goosechase to address the problem and work, but I am disappointed that neither could diagnose the problem. The problem is real and has happened probably 20 times over the last 1,000 miles; also passengers in the car have likewise experienced it.
Car sounded like popcorn popping but ran great with no check engine lights. We changed the waterpump, tested the altenator, and changed the balancer. After this the car did not make noise anymore but started stalling intermittently (say after 10miles)as if heating up and dying yet not heating up, with service engine soon light. The light said ignition module. The ignition module tested 20+ times and read good. Then once again read cam sensor. Changed cam sensor. Then once again light came on. Then changed all three coils. Still after 10 miles it stalls out and engine light on. We are chasing our tails and mechanics are helping us chase it. Any ideas from anyone out there???? Help, we are desperate. Last fall we changed the computer(brain), cam sensor and mass airflow sensor also. This car is killing me and its my only way of transportation.
car starts most of time. it starts slowly after turning key 4-5 times
when not on the gas or in park it acts like it want to die like the idleing is set to low.is there an idleing screw so i can idle it up so u dont have to have one foot giving it gas when in park or coming to a stop
When going along and need to increase gas just slightlty to maintain speed (whether in cruise or not) the engine will jerk but if I let off the accellerator and then press it again it is fine!
