I have taken very good care of my 97 S-10 since I bought new.
I live in Hawaii, so recently the last two weeks when it has sat for over 24 hrs. On cold start it first misfires slightly under power for first 3 or 4 minutes; than when warm it runs perfect.

I have one month ago changed plugs (condition was not present after plug change, used standard called for plugs) and also just now changed plug wires hoping that was problem, did not help.

Also recently ran Lucas fuel injector cleaner thru system and that did not help.

Thank you!

AC Delco ignition parts must be used on Chevys of this year. Anyother brand will not work properly. Try changing the distributer cap and rotor.

"Your response to my question on my 97 2.2L Chevy S-10 was INCORRECT, my engine misfiring on cold starts was answered by you to " try changing the distributor cap and rotor". Come on. My truck doesn't even have a distributor cap and rotor! I donated 10 dollars for this kind of answer?
Yes I changed plugs & wires, fuel filter and cleaned injectors. That is your best answer?"

I thought pear69's answer was a pretty good place to start a conversation. There's no need to get angry at someone who's interest is in trying to help you solve a problem. I'm up to over 25 replies for one person in trying to come up with a solution, and they are grateful, not angry I didn't know the answer the first time. If we were psychic, we would solve every problem the first time. Instead, we have to go by the tiny little bit of information we can pry out of you. Like many people, you didn't even bother to list the engine size. Why was that? Pear69 might have been thinking about a different engine. Again, I'm pretty sure he isn't psychic.

A proper response that might lead to a solution would be "I don't have a distributor; can you think of something else to look at". Has the Check Engine light been turning on? You didn't say. Snce 1996, misfires are detected by the Engine Computer. It will set a diagnostic fault code that will lead to the circuit or system with the problem, not necessarily the bad part. There can be fault codes that do not turn on the Check Engine light. Did you check for those codes? You didn't say. In fact, throwing parts at without performing troubleshooting steps, in hopes one will stick and fix the problem is the most expensive, least effective way to fix a problem. Since pear69 can't see or hear the engine, or perform any diagnostics on it, he is limited to what you tell him. Your donation is appreciated, but can you imagine how far that would get you if you took the truck to a shop? The majority of our interactions take place over days, sometimes even weeks. If you don't have the patience to help in the process, at least a little, you'll have to hold your computer a little closer to the truck so we can put our hands on it.

As for you pear69, don't give up. Rational visitors appreciate our help and with a little help, they can provide the details we need to figure out the problem. There's a lot of satisfaction in helping people undersand how things work and how they can get the problem fixed as quickly and inexpensively as possible. They know there is no incentive for us to give misleading information so we can sell unneeded parts or services. When you get those "thank yous", you'll remember why you're doing this.
