Frequently asked questions

How much does a check-engine diagnostic cost?
You'll know the diagnostic price before we plug anything in — we always quote first, before any work starts. The whole point of diagnostics is to find the real problem before you spend money on parts. The Davenport shop is at (563) 386-1343.
My check-engine light is on — should I keep driving?
It's smarter to get the code read soon than to guess. Our team reads the OBD-II codes, pinpoints what's actually wrong, and explains the fix in plain terms. We're open seven days a week, so you never have to wait long for an answer.
What is OBD-II diagnostics?
Your car's computer stores trouble codes whenever it detects a fault, and OBD-II is the standard system for reading them. Pulling the code is the easy part — the value is in interpreting it correctly so you only fix what's actually broken. That's the job our techs do every day.
Can you diagnose my car if I'm coming from the Illinois side?
Of course — Moline, Rock Island, East Moline, Silvis and Milan are all in our service area, and the Davenport shop at 1742 W Kimberly Rd is a short hop across the river. Call ahead so we can slot you in.
