Question about 1998 Chevrolet Blazer

2 Answers

I have a 1998 chevy blazer with a 4.3 v6 engine with 130000 miles on it. lately i have been having problems with the engine misfiring. It is usually fine once it gets above 3000 rpms, when you accelerate fast, and once the engine gets to operating temperature. any ideas?

I would start with plugs and wires if they have never been changed, and clean the terminal post of the coils. but also check exhaust after you start the car in the mornings..if you see a large vapor cloud ( some vapor in the mornings is normal.. even a "little" water my come out, but after 5 minutes or so it should go away). If you have a small gasket leak water will creep in overnight into the cylinder and cause the spark plug to be fouled up and then when the pressure and heat increase the spark plugs will usually get blown clean. Now if that checks o.k. then i would go down to the local Autozone and purchase a can of Sea Foam $10 and pour 1/2 can into half tank of gas and drive the car around for 30 minutes and let that stuff cleanout the injectors. can i get some feedback, thanks!

Idea one: it is not fine above 3000 rpm's, you just cannot hear the miss anymore. The most likely (and cheapest) problem is worn out spark plugs. If you replace the plugs and it does not improve replace the plug wires. If that still does not help you need to do a compression test to isolate the problem and do some heavy work. You must do something. If you keep running it the way it is you will ruin the catalytic converter. Catalytic converters are big bucks so fix it now rather than later. Good luck

How much will it cost for a mechanic to change oil pan gasket on my 1998 chevy blazer 4wd big v6 engine?


Gasket = $35 (permatex rubber)
Labor - my manual says 3 hours.
You'll have to be responsible for figuring out the labor price per hour depending on where you are located.
In MI, a garage is about $50/hr, and dealership = $85/hr
CA might be $95/$150/hr.

Parts are minimal on the job - its all labor.
Figure in about $20 for shop supplies... gasket remover, sealant, rags, etc.

2002 chevy blazer fuel consumption


Usually when it comes to bad gas mileage, an air filter change, fresh oil and filter, fuel filter and making sure you have no vacuum leaks....

Also, believe it or not, improper tire pressure will affect your gas mileage.

New spark plugs and wires are a "nicety" but if there is not damage to them, then they will be fine.
