Buick Lesaber, Lower then 1800rpm most time runs fine, Once in while surges high rpm's like driving fast 1900 & above rpm bucks /2100 smooth's out.


Need to take to a shop with a GM tech 2 or higher scan tool. These tools can actually display various sensor readings and voltages in real time and can be used while driving the car to recreate the issue. These are super expensive scan tools so most shops don't have them. Call around or bite the bullet and have a dealer do it. The money you spend on a correct diagnosis will be saved by not throwing random parts at it based on guess work.

Very bad idol and run condition.


sounds like a possible water temp issue... check your thermostat and/or water temp sensor. when you first start your engine the computer uses the water temp reading to do a 'cold start' scenario, more fuel. once you reach normal operating temp the fuel should be cut back. if the thermostat is not opening and closing properly this can cause strange readings from the water temp sensor (which is mounted near the thermostat)... unlikely the sensor is bad, but a possibility... more likely the thermostat.

2000 chevy blazer starting issues


swng,
1) Is the service engine soon light ever on when engine is running?
2) Per your description I would look at the ECT sending unit. It sends coolant temperature information the the Engine Control Module for proper fuel delivery for cold engine start. It may have lost its calibration.
Let me know.
Regards,

151 4 cyl , runs for 20 min perfect then starts bucking and seems like its starving for fuel and wants to stall. let it sit for half hour and its fine, starts right up. i suspect carb. malfunction have...


Could be carb but you should also look and make sure the fuel supply line is not running near the exhaust manifold or anywhere it could experience high temps as it may be boiling the gas in the line and could be "vapor locking" the fuel line. After it cools, the vapor dissipates and the unit has plenty of liquid gas then. Also check the manual fuel pump if it has one and make sure it is not faulting. The diaphragm could be getting weak and the engine heat could be causing it ti get soft and lose it's ability to draw fuel. Good Luck!
