does the temperature gauge show engine is very hot? could be a stuck thermostat, did you check for engine codes? this can be checked for free at most chain auto stores and give you insights into the problem.
Non so to speak without writing a book You just have to check for codes & start a logical diagnostic process of testing You input is critcal for a shop to understand the reason your there You do not won't a tunp-up or anything else You only want the immediate problem diagnosed & resolved Becareful not all shop know a lot or can solve all issues Be part of the solution don't just hand over the key & not be there sometime due their work on your car Ask questions & take notes
I Have a couple of questions. First question does engine surge when idleing cold? 2. Does engine start quickly without a lot of cranking, Cold or warm? 3. Do you have funny smell at highway speed, or after you stop? With out this info and your imput, I would only be guessing. I am retired mechanic of 25 years. and would like to help if u need me.
check your camshaft and crankshaft sensors. When defective, it may cause stalls, misfires, loss of power. Also have check the engine for vacuum leaks. Hopefully this helps!!
Does it feel like the transmission isnt disengaging and stalling the engine? If the transmission is automatic, it could be the lockout solenoid on the transmission. If it sticks, it will not disengage the transmission and cause the engine to stall when you come to a stop. Please let me know if this helps.
when the motor is idling the ESC (electronic spark control) module (also called ignition module) is responsible for the spark timing until the engine speed rises above 1500rpm when the PCM takes over. There is also a sensor behind the crankshaft pulley which sends a switching signal to the PCM & the ESC. Both of these are possible culprits. I suggest try an ESC (mounted underneath the three coils on left-hand side of the motor, and remmovable by removing the 6x7mm bolts holding down each of the coils and an 8mm bolt holding the electrical connector in ) from a junkyard from a know working car, if this does not solve your problem the crankshaft sensor is the next stop, To remove this you need to jack up the passenger side of the car and remove the front wheel, then remove the plastic cowling (being careful to unclip the cables from the cowling) using the 4x 7mm bolts at the top and side. When the pulley is in view remove the 24mm bolt holding the pulley on and the switch is behind it mounted on two 10mm bolts . good luck
