I like to work on my own cars. I have a Jeep Wrangler and doing a clutch job myself. When it got time to drop the transmission, and transfer case, I was having a bit of a hard time doing myself, not to mention that I didn't have all the bolts taken out of the bell housing. When Robert showed up, he knew exactly which bolts were still in, and what size the bolts were. He finished unbolting the bell housing, showed me how to strap the transmission down to the floor jack, and dropped the entire unit in no time. Robert is a transmission/clutch expert!! With over 20 years experience! I was charged 1 hour of time = 75.00 which is extremely reasonable!! I will definitely specifically ask for Robert to help me get the transmission aligned and back in. What a great service for the guy who likes to work on his own vehicles, but need a little help from a true mechanic. Thanks Robert!!

Jamahl was awesome. He was on time, he was professional, even having to work under my roommates unnecessary surveillance. (Sorry Jamahl). The work he did on my Jeep made a night and day difference. When I took it to drive again, it ran like it was brand new. And the cost? Less than half of what the dealership quoted. I'm happy. I will definitely use his service again!

All about Spark Plug Replacement

The spark plugs are an important part of the ignition system. When you turn the ignition key (car's key) on, it causes the ignition coil to generate the spark which ignites the air-fuel mixture in the engine cylinders to start the engine. The number of spark plugs in the car is the same as the number of cylinders, although some vehicle manufacturers will use two spark plugs per cylinder. Over time, the spark plugs wear out and require replacement. When the spark plugs wear out, it is harder for it the air-fuel mixture to ignite, resulting in engine misfires. If one of the spark plugs has failed, the car will still start and run, but it will run poorly. On some vehicles, spark plug replacement may be labor intensive and involve removal of the intake plenum.
