Started having hard starts a shaking in reverse gear loosing power wanting to stall on hills it smooths out and will run fine for a little bit she acts like she's not getting enough gas?


My Buick did that and I changed the spark plugs and plug wires and it corrected the problem. Hope this works for you. I had a couple of wires that shorted out when you were under power going up a hill. If you change the wires yourself only take one wire off at a time and replace with a new one and you will not get upset because you get the wires in the wrong plugs. Its hard to correct once you take them all off at once.

Your car is misfiring. You should not drive the vehicle while it is misfiring. If you want to DIY it you can start with you ignition system. Make sure all spark plugs, plug wires, and ignition coils are secure and in good condition.

Possible Service Engine Soon Light, Engine Stalling, or Hard Starting

Engine, May 18, 2009

RepairPal Expert Overview:
The RTV seal on the fuel system control modules may allow water to enter into the module. Water in the module can cause a short, which may cause hard starting, a crank-no start condition, or stalling, and the Service Engine Soon light may come on. If the engine stalls unexpectedly, there is an increased risk of a crash. Dealers will replace the fuel system control module free of charge. The recall began on May 18, 2009. The GM recall number is 08411.

The SERVICE ENGINE SOON light in my 1995 Pontiac firebird has been blinking for about a month and one day it just stayed on. At the same time the engine began to shake and now whenever it starts up it...


If your service engine light is on that means that you can find the problem by having a local garage run an engine diagnostics test,it usually runs around 50 bucks and is much easier than trying to find the problem yourself,and most of the time it is cheaper !

1999 denali-5.7- looses power and starts to shimmy...then shifts down and struggles to stay at speed...service engine soon light begins to flash and eventually comes on solid. This happens intermittently...


flashing check engine light is a sever engine misfire that will cause a catalytic convertor failure which is about a $1500 repair in your denali. Have someone scan the code for you and let us know the codes stores in the computer are. Could be as simple as a tune up to fix the problem or bad as a fuel pump

Flahing service engine light soon and engine began shaking


Yep 20 seconds on a machine turning 650 rpms is low on oil wil destroy the bearings in the pistons and crankshaft. Mechanics refer to the red check engine light as the idot light, because by that time it's to late the car ran low on oil and damaged the engine.Try putting some SPT oil treatment in and see if it will fix it temporally otherwise you may be looking for a engine overhaul. If the yellow check engine light is flashings you may have burned the rings up on the pistons and it is now burning oil, or more oil causeing it to throw a code for the 02 sensor. Good luck
