  1. After a cold start (i.e in the morning), does the engine rev upto about 1500 RPM and slowly settle down to normal as the engine warms up? If the rest of the throttle body is good, and if it is actually the IACV that is faulty, just replace the IACV. There's no benefit in replacing the entire throttle body unless the one on the car has a crack or irreparable damage.

    Bump of rear wheels

    First check the condition of the tyres. Check for previous puncture repairs that have the repair cord sticking out. Check for pebbles stuck in between treads. Check for bulges in the sidewall. Next, get the rear wheels balanced. Maybe a balancing weight has fallen off causing vibration. If none of them solve the issue, get the rear suspension checked out from a good garage.

    rpm problem

    Agree. If this started happening immediately after battery replacement, it's probably because the ECU was reset. Driving a few kms in mixed conditions (with AC on) should allow time for the ECU to re learn.
  4. Can you please explain the current law and how its different from what's explained in that discussion? Would be interesting to know.
  5. Hi, welcome to the forum. The "current scenario" is exactly what the OP of the quoted thread has asked. Old discussion or not, the law is the law. The advice given in that thread still applies. @Crosswind, since you are one of the first to respond in the thread, can you please confirm this is correct?

    Order Brand New Car

  7. The Potenza is a performance tyre. So softer compound = better grip + relatively faster wear. But like I've said in my RalliArt thread, they're the best tyres I've ever used. Then again my car is mostly a weekender and I prefer the handling and grip over service life. If your car is daily driven, you might want to settle for something for comfort and economy. However, it's your personal preference. The Potenzas will be significantly expensive. Especially if you're talking about RE003.

    Temperature indicator (blue)

    Your engine has a Coolant Temperature Sensor. It's basically a resistor that changes it's value based on the temperature of the coolant. The sensor is mounted somewhere on the engine in such a way that it's tip touches the actual coolant that's flowing around in the engine. So as the coolant becomes warm as a result of the engine running, the resistance changes. This signal is interpreted by the ECU. When it reaches a certain value (the operating temperature), the blue light turns off. It depends on the car, if it's petrol or diesel, type of engine and so on. Coolant is under pressure, so it can take more heat than when the liquid is under atmospheric pressure. A general range under normal operating temperature would be something between 90C and just above 100C.

    Requires a higher rpm to shift gears

    Hi @Jitha000, welcome to the forum! If the cold start RPM isn't stable, it could be due to carbon deposits in your throttle body and idle control mechanism. This explains why the car lacks power as well. When did you last do a fuel system clean up (tune up)? If you haven't got one done, suggest you do that first. Clean the throttle body, spark plugs, injectors and replace the air filter if you haven't done so in a while. Also get a diagnostic scan done while you are at it.

    @Arzath, welcome to the forum. Your question has been discussed before. Read this thread. I have merged it with your question. For more information, search the forum.
  13. What he meant was that the car turned into a bad old one quickly. Not that the car was fast. 🙄

    Suzuki StingRay Seat Heaters

    Why do you have to switch them on in the first place? Seat warmers are meant to be used during winter or very cold weather when the seats are uncomfortably cold to sit on or if you feel really cold. Your Suzuki Stingray is a car made for the Japanese Domestic Market. A country where it gets extremely cold in winter. In Sri Lanka, seat warmers are useless.
