Hi

I have a 99 3.3 Grand Voyager and need to adjust the gap of the spark plugs or replace as the car's been converted to LPG and runs ragged in city traffic when warmed up.

The Front 3 spark plugs are straight forward, but the rear 3...I can't even locate from the front / above.

Is it easy to access/remove them from under the car?

Whats the best option to access and change them?

Thanks in advance

Matt

 

remove the intake and wiper assembly or go under the van and get to them from behind

 

I just bought an '02 with the 3.8 engine and replaced the valve cover gaskets, plugs and wires. I did it all by just removing the wiper assembly (which took all of 10 minutes). Aside from the rear valve cover gasket the job was a snap. I couldn't believe all the wining I read when I did a google search on how to get to the back 3 plugs - an Aerostar is hard, this van is super easy.

 

an 01 to 07 is easy the 96 to 00 is not so easy for the back 3

 

back 3 suck!!!!!!!!!!!!!!!!!!! lol
