Had a JWT Popcharger + polished pipe fitted on my car for about 7 weeks now. Last weekend my engine light came on, took it to where I got the car from, plugged the computer in, was told it was something to do with the air filter, possibly something related to temperature but couldn't really tell. Anyway, the fault was canceled on the computer and all was well, light had gone etc. Anyway, week later, light's back on. I'm assuming it's the same problem as before. I'll take the car in on saturday to have it looked at again. It's a friends garage so will cost nothing to have it looked at. Just wondered if anyone knew of any issues with the air filters and the engine lights coming on. Have I just had bad luck in the space of a week or is this going to be a recurring problem or an issue with the way I've fitted the kit? Thanks.
