Ford Truck Wont Rev Up | Rear Suspension Blocks
I have a 2001 Ford Ranger 3.0. Recently replaced dfpv, old one burned up, also replaced hoses. The engine idles rough when cold for about 20 seconds then smooths out. Engine won’t Rev beyond 3000 rpm. At that point the engine will shake as if starving for fuel. Truck drives normally around town and at hi way speed. Won’t Rev past 3000 rpm in park.…
1998 Honda Civic Runs Bad- Code P0172 Fuel Trim Rich Bank 1
Live Chat: 1998 Honda Civic LX D16Y7 195k Automatic. Initially had a rough/surging idle problem, cleaned throttle body, injectors are good, new spark plugs, IAC valve good.

Previously threw a P1456 But that has since gone away…
2001 GMC Safari Coolant Leak and Rough Idle
Hello. My son has a 2001 GMC Safari with a 4.3 engine. He complained of a “rough idle” along with a coolant leak. Not knowing what the rough idle might be, I suggested he bring a new set of spark plugs. I listened to the engine then looked and found a bad left side motor mount, which I replaced along with the spark plugs. I…
Buick Regal Has Rough Idle
I have a 1995 Buick Regal. All of a sudden it seems to load up on fuel rough idle, have replaced a new fuel pump in and that didn’t help. Car has to be primed to get started. Once it runs it’s fine unless you shut if off then it has to be primed again before it will start. I am at a loss as…

1994 Ford F-250 Engine Light and Idle Problem
My 1994 Ford F-250 with a 5.8 Gas engine refuses to idle below 1500rpm. Is this a common problem in older engines and what might be causing the problem? I have a 15gpm hydraulic pump attached on a clutch pump, but the over revving is a fairly recent problem. ProTech: I’d first check for any vacuum leaks that might be causing a high idle. Also…

Chevrolet Traverse And GMC Timing Chains Replacement
A big thing we’ve seen a lot of over the past year or so, has been timing chain problems on the Chevy Traverse, Saturn Outlook, GMC Acadia, and Buick Enclave. All of these SUV’s have the 3.6 liter V6 engine with dual overhead cams. What is happening on these vehicles is that the timing chains are stretching which leads to correlation errors with the cam…
