Engine Performance problem
1999 Buick Lesabre 6 cyl Two Wheel Drive Automatic 218000 miles
my 1999 buick lesabre is heat sensitive. On hot days when parked on the blacktop it wont start. Acts like no spark as the engine turns over quickly and does not give any indication it is trying to start. If you pour water over the engine it fires right up and usually is fine. On really hot days it will run a bit rough on the freeway. I have changed the fuel pump and the electronic ignition module, the coils read within reccomended tolerances when tested with an ohm meter. Strangely the car even when it has sat for hours on the hot pavement feels very hot and steams like crazy when you pour water on the engine. It then starts up. Also never have any problem when the weather is cool.I live in redding california so 110 degree days are not horribly uncommon and have not doubt that blacktop temps exceed 150 degrees
have the same problem?
