Emissions testing service near Moreno Valley, CA

Our 2000 Toyota Sienna's engine light came on, took it to dealership in San Diego (we lived there until Jun 2010), they said all 2 O2 sensors (there are actually 4) would need to be replaced at a cost of $1200+, went to another dealer in San Diego and they mentioned 4 sensors would need to be replaced??? Waited until we moved to Hemet (wife's military) and had local dealership look at it, mentioned 2 sensors would need to be replaced at a cost of $1700.00!!!! because we lived in Oregon for a while there was considerable rust underneath the vehicle and there was a good possibility of the exhaust manifold needing to be replaced??? Took it home and looked underneath... not a stitch of rust - are you kidding me! Can't stand deceit. Asked around at our church, since we were new to the area, if anyone had dealings with an honest mechanic in town... was given Rod's name and #, a day later minus one sensor and $300.00 problem fixed!!! Hope this helps someone. Now my '72 Jeep

These guys were great! I would highly reccomend them. I had a 1:00 appt and was met with a can "do attitude". I was in and out in less than 30 mins. I just moved to town and when I found out they also do oil changes and tire rotations...there is no doubt that I have found my "go to" team here in Rancho. Please check these guys out you will not be disapointed!

Took my car there to have smogged today...they failed me and told me that I would have to pay $175.00 to have my vehicle repaired to get it to pass...I said no and went to another station where my car passed smog no problem.. Never again!!!

Today 8/8/2015 I took my truck to SmogZone at 12365 it was about 3:45PM, they closed at 4:00PM. I was greeted by John Yang who speaks limited English. In short he ran a SMOG Test on my truck, he never brought it into the bay to run any RPM tests. At 4PM he tells me "Oh your truck didn't pass." On the form he points to Smoke Check. He said "I do not know what that is, you must go to a SMOG Certification to have it checked, I'll charge you $35 to retest in 30 days." I was so upset, the truck has 36,000 miles, not a hint of smoke. I came home and looked up Smoke Check and found he is the one who enters Smoke Check. I plan to dispute the $49.75 he charged me. I should have known based on their previous bad reviews not to go there.
