Check the hose clips for tightness and examine the trunking for any cracks or splits and next all the vacuum system, the small bore pipes and fittings for cracks and missing parts. The best artifice to find a leak is to have the engine doling out and hot and then spray lighter gas /propane or brake cleaner approaching each joint in turn. If the engine rev s up you ve found your leak.
I bought it in July, drove it home from LA (to Utah), and the problems started tersely after I got it home.Any further encourage you can come up with the money for is appreciated. I don't know what else to pull off but tolerate it back to the dealer. I know I've got the shop foreman functional upon it at the dealer, but I yet setting its pushed to the assist as its obsolete and everyone loses in this situation.
with I begin the car, the engine surges going on amongst 1200 and 2000 rpm help and forth. I distorted the IAC and the TPS behind no modify in symptoms. I have noticed that several Lexus SC's have this similar issue. Prior to this I would have to adjust the idle rapidity screw to degrade the rpm and it would support for a while. Now, the engine is forever surging to the reduction where I cannot steer it for distress signal of damage to the steer train. Any experienced solution?
