Misfires again

warped head or block? Valves not sealing?

Sunday night would be heroic. Rent a car for at least a week and make it easier?

Or trade in for token value?

 

Yay! Another new thread to an existing thread so can bounce back and forth like all of the lord of the ring movies. I’ll make the pop corn!

 

Now for round two

Once again the plugs, coils and egr proved futile.

Rebuild this time including pistons and rings. Or else you can shoot for the hg record, currently three before an engine replacement. But by Sunday a hg may be the quick and dirty.

 

Retiring a 2012v5 might be a losing proposition for the next year or two as long as used cars are in short supply. If you change the engine diy a $3k fully rebuilt engine shipped for perhaps $500 would renew an otherwise good v. Assuming the brake booster and hybrid battery were already handled.

Think of it, no more oil burning, no more cold start misfires and no oil leaks. For another 150,000 miles or to simply add $8k to the private party resale value.

 

Hello,
Did you buy the spark plugs from eBay or Amazon? Two years ago I bought a 2010 with 103,000 miles, the previous owner took excellent care of this car and did the maintenance himself. He said he just replaced the spark plugs when I bought it. At about 125,000 miles it started to misfire badly so I replaced the spark plugs with original Toyota brand from a local dealer. The plugs I took out had Toyota markings all over them but look different from the dealer plugs, country of origin different, lettering faded and not sharp, leaking from porcelain at base. The car now runs like new and has been for 10,000 miles. I stumbled across a YouTube video channel talking about counterfeit Toyota parts that led me to this. I mention this because it looks like you put about the same amount of miles after your spark plug replacement. If you bought the plugs from a local dealer then this would not apply.

Also with that many miles instead of trying to clean an old and possibly worn out EGR I would recommend replacing the EGR valve with a new Oem Toyota one and having the software updated for this, TSB-sb- 0027-16. If you want to eliminate the EGR valve as the cause you can block it off where the metal pipe from the intake manifold bolts to it with a thin putty knife. Remove the top bolt, loosen the bottom one, insert the putty knife and tighten the bottom bolt. Don’t drive it around like this, just temporarily to eliminate that part as the cause and don’t try to just unplug the harness connector to test this.
Hope this helps in some way.
