It could be - if it was installed incorrectly, the timing will be off and you should notice a change in the vehicle's performance. It is more likely there is a sensor problem that may have been caused as a side-effect of the work. Have the trouble codes checked to pin down the issue.

My aunt has a 97 nissan pick up she said the engine light is on and the belts are noisy. do u think that a nissan with 87000 on it would have a problem with the timing belt or just needs new plugs?


The check engine light is warning the driver the computer has found a problem that will affect engine performance or emissions. The light would not come on for a problem with the timing belt or accessory belts.
87,000 miles is around the time most companies recommend replacing the timing belt.
You would need to have the computer scanned for trouble codes to proceed with troubleshooting the problem or problems.

"emissions garage" warning light


this could be due to a large variety of possible different faults, the only way to tell is to take to a garage for it to be plugged in to a diagnostic code reader. Not always serious, somtimes as simple as an engine coolant temperature sensor fault, cheap to buy and quick to replace.

Emissions warning light stays illuminated while driving vehicle is a holden vectra 2001 and not oldsmobile as below. could not find a listing for holden.


The warning light has two states. A blinking light indicates a critical problem with gaseous emissions from the engine that is likely to cause permenant damage to the engine, exhaust sytem or catalytic converter. A blinking light must be remedied immediately, and the car should not be driven in this state, at the risk of causing serious and permenant damage to the engine, exhaust and/or catalytic converter. Repairing or replacing these parts can be extremely expensive. A reputable garage or a Vauxall/Opel garage should be able to diagnose and repair the problem.

A solid (unblinking) light indicates a non-critical fault in the emmisions exhaust system. Many faults are covered by this light including failures in emssions sensors, temperature sensors and a variety of other parts. This usually results in a higher than average amount of environmentally harmful pollutants being expelled from the car, loss of power and/or gradual damage to the engine, exhaust and catalytic converter. While the car can still be driven with a non-critical emmisions problem, it is highly recommended that the fault is diagnosed and repaired at a reputable garage or Vauxhall/Opel garage.

Lambda probe fault possibly


I bought a 2000 polo 1.4 yesterday after having an MOT. The warning lamp came on today but the car is running fine. Whether its the Lambda sensor or just the light itself is a common fault, I think garages turn off the lights to get it through the MOT then they come on again in a day or two!
