Not a big poster but I've been around a while. I own a 89 4RUNNER 22RE. Got a quick question:
Has anyone here attempted to remove their EGR system on the 22re?
What was the results?
What I found Searching:
Pinging due to high cylinder temps.
ECU retards timing due to ping.
....but I seriously doubt EGR removal is going to cause ecu to go retarded. I'll accept my bad gas milage, but pinging I question..... thoughts? Experience?
I blew a head gasket last week so I sent the head off to the shop for a valve job, seals, porting, ect.. I had mention to my buddy about wanting to get rid of the EGR system, and he took my EGR pipe and cut it up to make block off plates. So now I have no choice. I'll let everyone know the results.
