Oh Boy Did the Tune up today.... Sort of.

GirlBear · #1 08-31-2005, 02:27 PM

This morning I started her up. Sat for a minute as my passengers got in and buckled up. Went to take off and almost stalled. No power seemed as tho she was gonna die. "service engine soon" blinked franticaly. Then as i entered the highway she sputtered some more. oh and the oil pressure was going between 40 and 60 almost reachin 80. I stopped gained my senses and continued on my journey. She runs ok now oil pressure is between 40 and 60 more like 50ish. Still hesitates a little. I got pissed off and smoked'em around a corner. So she is still in there. And Sevice Engine light is on solid now. Any clues. Im changin oil and filter. dont think it is related to my problem tho. Plugs and wires were replaced only a few months ago. could the hesitation be fuel injector or filter related????? Any help will be much appriciated.

Could be fuel filter, could be an o2 sensor either going whacky or sensing a real issue. Could be carbon built up on the plugs but as you said they are pretty new. Maybe bad gas? Try filling up with super and seeing what happens after that tank. But what you need to do most of all is get those codes read and find out what the problem is asap! Autozone does it for free! Come back to us with the codes and what they mean and we might be able to help farther but I am sure you will have it figured out by then! Good luck

Stop leading her on a wild goose chase and wasting money. The check engine light is on and you are going to ignore it??!!

The check engine light is on, you tell her to go to Autozone and have the codes scanned for free and come back here with the actual code.

You don't just start putting random ideas forth to confuse people. You are only making her situation worse.

I told her she can get the codes checked out! How am I making her situation worse? I gave her some probables of what it could be, I didn't say this is your issue. If you read my reply I did tell her to go to Autozone and get it checked out. I wrote it could be. I never said get this and that checked out and replace this. I said "could" be. You do understand the definition of that right??? GirlBear, I apologize I didn't just write go to Autozone and get the codes read first before I said anything else. Enough said

here they be. I read the other thread were the guy was havin same sort of issues and MAF sensor was answer. I must add that When I reset the memory by disconnecting the po+ cable to battery. She ran real good. I was thinkin about reseting it again. or will that just make things worse?

MAF sensor.. do you use a K&N filter? I know that K&N say it doesn't, but the filter oil can clog the sensor and make it go wacky.

Over oiling is usually the culprit.

BlazerLT · #7 09-02-2005, 06:38 PM

This is the passenger side manifold O2 sensor is bad and needs changing. If it was the MAF, both manifold sensors would be causing errors.

What is needed here is a new O2 sensor and a tuneup.

Listen to this shit. I bought some Gumout fuel injection cleaner. And wires and Plugs. Put in the gumout. Ihad a bunch of errands to do. Drove about 50+ miles all together. go home. Eat. Start her up no "Service engine Soon" light. Runns perfect again. I'm gonna tune it up tomarrow. but Wut the hell. did that cleaner fix it?

You really need to start listening Girlbear.

Replace that O sensor and do a tuneup including:

Fuel filter
Spark plugs AC Delco Platinum only
Cap & Rotor
Air Filter
PCV Valve

I do not have enough info or knowledge to disagree with blazerLT, but I can say this: I had the same codes on my 97 and the same thing happened. Went up a big hill and got O2 codes and P0300 misfire codes. Erased all the codes, ate dinner, and it has not happened again since (now over a week later). I would not replace the O2 sensor. If the O2 sensor is bad, the O2 sensor codes will most likely reappear on your truck very soon. THEN, I would replace an O2 sensor, but not before. Unless you have 50 bucks to burn on O2 sensors you may not need...

no no no no NO NO no. DO NOT I repeat DO NOT disconnect the posative battery cable. If unhooking a battery, always unhook the negative first, and reconnect the negative last. You dont want the wrench to touch ground when unhooking the + pos cable. Always unhook the nagative. Please. You may think its not important, but if it happened to you once, you would learn fast. I had a buddy short circuit a battery straight across the terminals with a wrench, and I am not kidding you, sparks flew to the heavens, and that wrench got so hot, it melted to the battery, I thought it was going to blow up. But anways, just do a tuneup like everyone says. Plugs, wires, fuel filter, air filter, (I dont know what year yours is), and check the distributer and rotor if it has one.

I'll be honest. If it were me I probally wouldn't do anything unless it happened again. Might have been some bad gas or peice of dirt in the injector. But since you already have all the stuff for the tune-up it would not hurt to do it. But I would no replace the O2 sensors just yet unless you have repeat codes from them.

agreed !!!

That is pure laziness.

Sure she needs to replace the Passenger manifold O2 sensor, but saying she shouldn't do anything other than that even though she is in need of a tuneup is just you guys pushing pure laziness and sticking your head in the sand.

Telling people to not properly tuneup their engine is ridiculous and the random misfire could be from the lack of a tuneup.

crossing your fingers and hoping it will go away is just someone that is too lazy to keep their engine in perfect running order and wants other people to follow their poor thought out ways to make them feel better.

Girlbear, replace the sensor and do a full tuneup. Get that nice blazer working and firing like it should be.

To everyone else, shame on you.
