Hello,

I have quite a few problems with a 1994 Volvo 460 1.8L

- When hot, the engine sometimes does not start up

- the ABS light is on almost always, when I press the brakes while starting the car it goes off but the car makes some weird noise at random, it sounds like the ABS while breaking but it doesn't actually brake

- When idle, the RPM go up and down periodically about each second. When the motor is cold I have to push the gas pedal a bit so the motor doesn't die. Sometimes I have to do this for several minutes.

- The lights on the dashboard flicker as if the battery was low, but it isn't.


I should add that the Lambda sensor was replaced but it didn't help, and the battery was charged and it did still flicker. I tried another ECU but it didn't change anything.

hi :banana: idle problem -volvo fix amp mod fitted near ecu for stepper motor
abs problem-light should be on when first start up goes out when selfcheck done,
noise would me self check actuators and pump if light stays on problem.starting problem temp sender? need fault code first all information wrote down so we can help :grouphug:

Can you explain a bit more about this please, because I also have an uneven idle. Would be nice to get it fixed!
