The Premier Automotive Engine Troubleshooting Resource Site.

We Share DIY, Automotive Engine Repair Information.

Helping Solve Automotive Engine Problems, For Everyone.

Engine Rebuilding, Basic Engine Machining, Technical Information, Diagnostic Troubleshooting, And Finally, Testing With Possible Solutions.

So, Danny’s Engineportal, strongly suggests, that a visual inspection of the engine, is the first step in proper diagnostics.

Is a wire loose ? Did a vacuum line fall off ? Do not look for a complicated solution, to a simple problem. It is common to have a problem in one area, that impacts three or four others. So, with a little knowledge, and our help, you should be able to solve most problems yourself.
