Since there was some 'washing' going on, pay special attention to ground
points. I've had some systems which reacted to weather like an old man's
arthritis! The fact that it worked for a while then degraded suggests
corroded gound points or bad connectors.

I got another auto electrician he said he checked and discoverd that whenever the car stalls current is not been supplied to the coil on the plugs and when he has that kind of issue what he does is that he will change the ECU of the vehicle and reprogram the car to work with the new ECU.

Please you will have to read a lenghty question.I went to where spare parts is been sold and was given a number to call I called the guy explained my situation to the guy he too said he has to change the ECU which he did I now scanned the car got P1698 P1391 but no P0725 which keep stalling the car but the car idles roughly.I checked what p1698 means discoverd that has to do with transmission the guy said we should check TCM fuse discoverd its blown replaced it back but car still idles rough so he changed fuel filter changed ignition coils and changed nuzzles car still idles roughly so he opened the air cleaner and used injector cleaner to clean what he called throttle position sensor and turned the black adjuster on it fit it back car still idles but on acceleration to like 3000 rpm smooths out I complained he said since the car still idles roghly he said he will open the top cylinder to check the valves cos if they are not sitting well the car will not idle well.so i told him to hold on drove the car around its more driveable so I scanned the car, each time I scan it gives me different codes but this are the codes p0205,p0123,p0352,p0354,p0357,p0186,p0765,c2459,p0 100,p0400,p0048,p1391 what can you advice cos I suspect the car is driveable because he adjusted the TPS what can be the effect of the TPS adjustment

Read and follow DougW's suggestion and find a mechanic who knows what
he/she is doing.
