Dallas LT5 Shop

[DallasZR-1]

I just wanted to put in a good word for David Mullins Corvette in Garland, Texas. He seems to know his way around an LT5 and quickly tracked down the source of my car's misfiring. I always appreciate a mechanic who walks me through their thought process and who clearly loves their job.

My ZR-1 had been running poorly for so long (stumbling at low RPM, misfiring when hot, total lack of punch), I had almost forgotten how fast she was. That first WOT had me cackling like a mad man.

So what was the issue? Hey Pete

Embarrassingly enough ... 23-year-old spark plugs.
