Best Way to Clean Injectors?

[SHOwener1986]

My 95 MTX starts all the time but sometimes it takes 2 turns of the key, whats the best way to clean the injectors, and I will be doing the valve cover gaskets at the same time, so I will be able to hopefully clean them well. Thanks A lot

What makes you think that the injectors are in need of cleaning? Hopefully you're not automatically blaming the poor starting on the injectors.

Remove them and send them off to a shop that specializes in ultrasonically cleaning them. They typically include some new parts and try to get them flow balanced. They ought to provide you with a chart and all the flow measurements.

Good idea to make sure you'll have new o-rings on hand before you reinstall them too.

If you want a cleaner in a bottle then the "complete fuel system cleaner" which used to be called SI-1 (still has SI-1 on the bottle in smaller print) from redline is very good. Dump a whole bottle in a tank. I used to be more religious about using it for maintenance. Used to do a fifth a bottle in every tank. Then went to their minimum dosing to pinch a few more pennies. Don't use it in every tank lately because I'm lazy and am going to get a couple sets of injectors ultrasonically cleaned one of these days....maybe sometime this year. FWIW, I turned my dad on to that stuff years ago and he used it religiously in his 2000 toyota tacoma from day one. His local supplier stopped stocking it and I began to hear about it. A lot. My 69 year old father was practically beating down my door demanding I tell him where he could get the stuff. Hasn't had it since summer and swore the truck ran "better" and "smoother" with the stuff. Had the company buy him half a dozen bottles for starters to quiet him up. He's happy once again. Since a Long's drugs on the way home has the stuff. At the best price and tends to be good about keeping it in stock, I'll just pick up a couple bottle for him every month or so or I WILL hear about it hehe.

Another option is getting a product that comes in a pressurized can and screws onto the scraeder valve and lets your engine run on the cleaner for a few minutes. There are a few different products on the market. They all have a kit that has adapter fittings for various cars. Some are quite expensive though I once found one that wasn't too bad. Never bought it though. Said to give a good cleaning. 3M has one of the good ones. Their adapter kit was one of the pricier ones though IIRC.

since Ill have the intake off the car while Im doing the valve cover gaskets, Ill just get the injectors cleaned, I think im gonna go with the untrasonic cleaning, also will 3.2l injectors work with the 3.0? Thanks
