91 4 cil Injector bad?

Sounds like the plug lead or the distributor cap is cracked or tracked to ground. Ignition loss under acceleration means the spark is taking "the easiest (read: lowest resistance) path to ground" elsewhere than across the plug. When the engine starts to work harder, the air-fuel intake increases and presents across the sparkplug gap as a higher resistance.

How can I tell if it is ignition loss. Wouldnt a bad fuel injector do this, a lean condition. My bad cilinder started to burn white.

It was the plug wire, crappy 3 yr old 12000m on them after market junk. I am sick of aftermarket junk, My aftermarket thermostats last 3 yrs., plug wires 3-4 yrs. I bought 2 plug sockets yesterday before returning both, they would not hold the plug in. They were Tiawan crap. You cant be sure of aftermarket junk anymore. I know this has been going on for years but it seems worse. So my new wires and cap are aftermarket 70$. I wonder how long they will last. For one lousy bad 3$ wire it cost me

Yes, its a bit depressing when you buy in good-faith aftermarket parts and they are garbage. I mean dont they too have to live up to some informal industry standard? 3 yrs is not good enough.

I bought an aftermarket t'stat once and it was faulty (stayed shut). A lesson learned.

Sure is not worth saving a couple bucks using cheap parts... Lesson learned. Glad you got it fixed.

What would you consider "non critical bits"?
