Engine Diagnostic help

[Steve R]

I wonder if anybody can help me? The engine in my Trophy sounds rough on tickover and when cold occasionally the engine warning light flickers or appears on the dash for a few moments. I've had the engine checked on a diagnostic - specifically the injectors - and it appears to be running fine. The engine pulls well and does not appear to be down on power. The car is run by a racing team who changes the cam belt as a matter or course during the build. They are not experienced in the 182 unit and im concerned that the timing has been set incorrectly



Is this a common problem and if so, what is generally the cause?

Thanks in advance

Real common problem. Happens too many times. Where abouts in the UK are you based?

As TonkaTruck says, it's quite likely the timing is out. If someone inexperienced [with F4R engines] attempts to set the timing (and doesn't use the correct Renault locking tools) then there's a very high likelihood that the timing is off. That said, I've always found that the F4Rs do tend to run a little lumpy and rough on cold tickover but it might be worth getting it checked over by a Renault specialist.

Thank you Chaps. I'll get the timing checked asap.
