Injector question

What are the tell tale signs of fouled injectors?

An injector with bad seals will be spraying/leaking fuel terribly. But as for an injector thats no longer opening/closing i am not so sure.

If they're original Renix injectors with over 100,000 miles, they need to be replaced with later model ones.

Well my truck is spitting and sputtering with about 95000 miles on it and more than likely are original.

Couldn't hurt to replace them if you have the funds.

Hey just catching up on old posts, it wasn't the injectors, turned out to be a cracked rotor cap, and a bad oxygen sensor x.x

Seems to ba alot of that lately oin all of the forums. People chasing their tails looking for issues in the injection system when normal maintenance items have failed or not been replaced at the recommended intervals. Especially distributor caps, the ones with aluminum contacts.

Every 30,000 a 4.0 should get new plugs. I like NGK coppers. Can't go wrong. No need for Miracle Plugs. Napa Belden plug wires with their Premium cap and rotor which have the brass terminals.
