First off Id like to say hello from Wilmington NC.I have been lurkin on and off between a few different sites for tech help when i needed it.Well its time and I think this is the correct choice.Now down to the nitty,gritty.My journey started in 1997 with the purshase of a 4 Runner Limited.This has been the BEST car in my garage for being driven daily(228,000 and change on the OD).Up until now there hasnt been anyhting i couldnt trouble shoot or fix on my own(of course with a manual and code reader)and a killer set of tools.I have ran into a problem and need some fresh input,I have developed a miss and my code reader points to a missfire on cylinder 2.Now the problem i looked at the plug(replaced them in Oct.)& it looked great.Checked the wires(good readings and checked out with a spark tester.(Also replaced in Oct.)Coil packs check out,and thats where im stuck.Im thinking the Injector in cylinder 2 is bad or fowled so i have already put some Lucas cleaner in a fresh tank((today).So im asking for someone to point me to another cause for a single cylinder to missfire?Any help would be great as my girlfriend drives this to work and its driving her crazy to be in such a nice ride thats running like junk.thanks people.

 

Welcome to YT man. Hope someone can help you out with your misfire.

...and a bump to get you to the top of the list again....

 

Well its looking like im going to break the rule of mine(#3 rule)and take it to the dealer for a check up.Not that i have anything against the Toyota dealers but im a DIY all the way type,that way i know it is done and done right by my standards.Thanks for the bump psraff(Nice rig wish i could talk the G/F into letting me trick the truck but she says thats what the mustang is for)LOL

 

Did you clean the MAF sensor?

 

getting ready to do so now and recheck to get the code number its giving me.I was just going off the fact it was saying ther ewas a misfire on cylinder #2 didnt bother to look at the code number.

 

If you haven't, read this https://www.yotatech.com/forums/f2/s...tation-211546/ it may have the answer for you.

 

Sorry for the long delay but the codes i got Are P0300,0301,0302,0303.So by the book i get a random misfire,misfire on cylinders 1,2&3.Just cleaned the MAF and waiting on the ECM to reset(unpluged battery).Cross the fingers and hope this works.I would hate to set fire to my toyota..LOL J/K.

 

Ok im still dumbfounded.Maf is spotless I almost used a whole can of cleaner(MAF cleaner)but im still getting the lope and lack of power and CEL is flashing then goes off just to come back on.Im giving in tonight but ill check codes again tomorrow and check the #1 coil pack.thank people for the help.

 

Turns out its 4 bad injecters,After I replaced the coilpacks,and fuel filter I broke out the engineOscope to listen for vacum leaks and TADA super loud ticky ticky tick comming from the trouble cylinders.So at $120 a pop im guessing i have my weekend hammered out for me with a 6 pack of injecters and a case of Barqs rootbeer.

 

All good.Shes running like the day i drove it off the lot in 97.
