I got a 92 Toyota Camry LE 2.2L 5S-FE engine. The check engine light is on and the code is 71, EGR valve. I have trouble taking the EGR valve out to clean it. The trouble is trying to get the bolt that connects to the pipe loose. Any tips? Thanks.

 

try runnine some sea foam through your pcv valve it usually hits the egr. but, being a 1992 its quite poissiable that your egr needs to be replaced.

 

I have run Seafoam through the brake booter vacumm line. I'll try running to the PCV valve worth a try. Thanks.
