A rough idle and even an emissions inspection failure for high HC and CO can be caused by improperly adjusted valves. Also, exhaust valves may become to tight which can lead to valve failures. Our technicians tell us that regular valve adjustment inspections are a must.

Most reported Toyota Tacoma problems
At higher mileages, an anti-lock brake system wheel speed sensor may wear out and illuminate the ABS warning light. It is recommended to replace the sensor with a factory part and be sure to clean all rust and debris from the mounting area because the mounting distance is critical. Failure to do so may result in the new sensor setting false trouble codes. Be sure to check the condition and runout of the front wheel bearings on the 2WD and 4WD vehicles and the CV joints on the 4WD vehicles since worn wheel bearings and/or CV joints can cause the ABS trigger rings to rub against the ABS sensors and damage them.
A loss of power on the freeway may due to an internally leaking fuel pulsation dampener. This commonly occurs on higher mileage vehicles.
At higher mileages (125,000+) the mass air flow sensors may cause the vehicle to idle rough, run rich and even stall. It is recommended to replace the mass air flow sensor with a factory unit because the aftermarket units have very mixed results.
At 125,000-150,000 miles, the Brake Master Cylinder may need replacing. It is critical to adjust the brake pedal to Master Cylinder pushrod clearance or the brakes will drag and over heat.
I got rid of my 2009 Taco because of noise during nonacceleration around 70 mph. I'll be darned if the 2011 doesn't do it also! Come to find out that it is a known problem that they didn't tell me about until I had traded vehicles. It is a serious rattle during times of slack accelerator pedal at higher speeds.
occasionally my check engine light comes on saying the catatlyst is below the threshold but when i smogged it the other day it still had numbers even far below the average so it has better emissions than average. problem fixed by just resetting the light
Running lights crack but headlight housing does not allow replacement of just daylight running lens. The entire front headlight assembly has to be replaced. Approximately $900 OEM repair. After market lights range from $150/pair to $400/pair for top of the line HID lights. Toyota charging $350 - $400 per light assembly and this is a manufacturing issue.
I believe I had this problem reoccurring for the longest time. I had o2 sensors and catalytic converters change but this problem is reoccurring all the time. I had an MAF go bad and had it replaced and this will pop out again. Can someone help me?
