Autobytel.com will tell you of any known recalls for your vehicle. You just type in your vehicle information and it pops any recalls up right there for you. You can also check with the national transportation safety board but I would check the website first.

There was a TSB, not a recall on this problem. To be sure, calling any gm dealer would require them to tell you.

How to change spark plugs


You will need a 12 mm wrench and socket, a 10 mm socket , an extension and the socket for your spark plugs, and an intake plenum gasket. Start by pulling the positive cable from your battery. Next pull the intake cover off the top of the motor. On the drivers side you will see 3 coil packs or "cops" ( coil on plugs) those have two 10mm bolts, one on each side. Remove those , pull the coil, unscrew your spark plug with your socket, and replace.
On huge passenger side you will have to remove the upper intake arch (plenum) to get to the remaining three plugs. Repeat process from the drivers side. !!!!replace your intake gasket when you remove the upper plenum or you will have a vacuum leak.

What is the easiest way to replace the pigtail on the harness that conects to the upstream o2 sensor on a 1996 dodge grande caravan 3.3L


Just cut and splice. 1 black wire, 1 grey wire, 2 white wires just color match. You may want to remove the upper intake plenum to gain access though. Might as well plan on replacing the o2 sensor while your at it. If the plug got melted because it rested on the exhaust manifold, you probably wont get it unplugged. Not sure where to obtain a replacement plug though. You may have to hit some salvage yards.

Sounds like you have a bad vacuum leak. Check all hoses and the intake manifold. Not saying this is your problem , but I just replaced a plastic intake plenum because the converter was clogged and when the egr valve kicked in it melted a hole threw the plenum. And ofcourse this car ran like ****.

Removing the intake manifold for spark plug change? How do you do it i cant get the stupid thing off.


In truth it is not the intake but what is referred to the "plenum" when removing you will not have to deal with draing down the engine's cooling system as you do when you remove the "intake"
Start by removing the battery ground, look at the plenum and all of the cables, wires, hoses and such that cross it and plug to it; I expect you'll need to remove throttle cable too. The plenum will be bolted to the intake, I expect it will have a bracket in the back too. Take digital photos before you start, note what plugs to wear, tag connectione to get them back to wear they go. Take your time and be patient with the process.
I hope this may have helped,
Tom

What does a MAP Sensor look like, where is it located and how do I replace it on a 1996 Plymouth Voyager, 2.4 ltr engine?


So you dont know where it is, or what it looks like, but you know its bad, and need to replace it? Its on the end of the intake plenum, 3 wires, once you find it, you will figure out how to replace it.

I need to change my spark plugs on a 04' Mitsubishi Montero Sport V6. I need to know which bolts to take off of the intake manifold to replace the spark plugs


If you'll need to remove the intake (or plenum) from the engine there are @ 8-10 No. 12 nuts and or bolts which hold this in place. There are also 1-2 bracket (check by the firewall) you'll need to unbolt too. Be certain to replace the gasket that is found between the plenum and the intake and do not over tighten these nut/bolts only 20ft pounds or so. If you do remove this you'll have to remove the air inlet, throttle cables and remove hoses from the throttle body, some of which carry coolant to properlly preheat the air before enteringthe engine. I have worked on several early 89-93 Monteros without having to remove this for plugs; perhaps different under the hood of the sport.
I hope this may have helped,

Hello, i need to know what all is needed to chage the rear spark plugs in my 04 sante fe? do i need a new intake gasket ect. thanks in advance.


You shouldn't need any of that if you have the right tools for the job such as a swivel, extensions and the right socket of course. It wouldn't make any sense for them to build a vehicle in which case you would have to disassemble things from the cylinder head to replace a few spark plugs
