I'm just looking to do some routine maintenance on the car before I hand it over to my little bro. I'm thinking about taking off the EGR valve and soaking it in carb cleaner, but I'm wondering if it's worth the trouble. It's a '95 7a with about 180k mi on it, and it's never been cleaned before. There's no CEL on though, so I'm not sure if it's even dirty to the point where it would make a difference.
Thoughts? |

Got this from a manual a downloaded a while ago:
"1989-95 ENGINE PERFORMANCE Toyota EGR Function Testing All Models EGR VALVE 1) Disconnect vacuum hose to EGR valve. Using a hand-held vacuum pump, apply vacuum to EGR valve with engine at idle. Engine should run rough or stall. If engine does not run rough or stall, check EGR valve passages for blockage or faulty EGR valve. Clean passages as necessary. If passages are clear, replace EGR valve. 2) Install vacuum gauge to ported vacuum port to EGR. Raise engine RPM. Vacuum should be present. If vacuum is not present, clear vacuum port of blockage." Best to find out whether it needs a cleaning before you even pull it out. But Box is right, easy on the A |
