Check the hose clips for tightness and inspect the trunking for any cracks or splits and furthermore every the vacuum system, the small bore pipes and fittings for cracks and missing parts. The best quirk to locate a leak is to have the engine running and hot and later spray lighter gas /propane or brake cleaner vis--vis each joint in turn. If the engine rev s going on you ve found your leak.
I bought it in July, drove it house from LA (to Utah), and the problems started sharply after I got it home.Any additional incite you can present is appreciated. I don't know what else to do but put up with it back up to the dealer. I know I've got the shop foreman dynamic on it at the dealer, but I yet character its pushed to the back up as its pass and everyone loses in this situation.
I don't have any check engine lights unless I unplug the MAF sensor. with the MAF is plugged in subsequently the car will stall unless I put my foot upon the accelerator. There is also an intermittent popping solid coming at idle.
