Hi guys. So I bought a Vt commodore in January, all was running fine till about 4 says ago, towed a trailer and Now it runs sluggish like it kind of jerks forward from stationary to 30km/hr then it runs normal, changess gears fine but then drive for a bit n the engine light comes on n this really loud rattling sound starts when I put on the accelerator, no matter if I turn off the car for 5 minutes n turn it back on I'll start driving then the engine light will come on again. There's also a kind of airy noise coming from what seems to be the dash but the aircon n heater aren't on. I've just also done a major service to the car with the plugs leads oil, transmission oil, radiator etc. I don't know what the hell is going on but it's starting to bug me n it loses soooo much power when the engine light is on can't accelerate fast or anything. help!!!!! Please!!!
