How do i fix a misfire on a 1996 suburban


Hi Yvonne, I'm glad to help!

The first step when you have a misfire is to see what is causing the misfire. Technicians always rules out mechanical failures before moving on too Electrical issues. What you need to do is check compression on cylinder 2 and see if its good. Remove the spark plug and test it with a compression tester. It should read somewhere around 150 PSI or more. Check it to cylinder 4 and make sure the reading are close they must be within 25 %. If the compression is GOOD then you'll need to move to the electrical checks. Here's how you rule out parts. It doesn't matter if you have plug wires or coil-on-plug. SWAP the parts from cylinder 2 to cylinder 4 and start the engine and if the misfire moves from 2 to 4 then you know its either the spark plug the spark plug wire or the coil pack if you have a coil instead of a plug wire. If the misfire does not move and stays in cylinder 2 then it could be an INJECTOR, WIRING ISSUES, COMPUTER DRIVER. As you see Yvonne it can be a lot of things that can cause a misfire. Hope this helps and have an awesome day Yvonne.

1996 isuzu rodeo keeps reading #2 misfire runs good xcept when cold it hesitates most times or jus occasionally hesitates then the check engine light flashes and its guzzling gas i only got 50 miles on a...


A misfire alarm typically means the coil pack mounted above the sparkplug indicated in the misfire had gone defective.

To test it, swap the coil pack with another cylinder, and see if the misfire goes from #2 to the cylinder you put it on.

If the misfire continues to be on #2, then consider changing the sparkplugs.

I hope this helps.

I have a 97 chevy tahoe 5.7 i just did a intake gasket due to the one given out truck ran fine befor i took it a part but now it runs and throws the p0300 code has a slight rough idle


P0300 random misfire, slight rough idle good , by the way your repair is good you dont want a identified misfire, Lets start by what it is not. Not a misposition sparkplug wire you would of gotten that cylinder code, as misfire, Oh try this got carburator cleaner? spray safely along the intake gasket, How about inspecting the vacuum hoses especailly at the map sensor. Here the thing you got. a vacuun leak. on a 5.7 a vacuum leak causes random misfire, by definition P0300 means 2 cylinders or more. By experience its a vacuum leak

Do an injector balance test and a cylinder leakage test. Lets make sure its not fuel related. Most important lets make sure you don't have a vacuum leak.
