Hey there, new to the site.

I own a 1988 Suburban 1/2 ton. Family man with 6 kids and 3 dogs. Looking forward to checking things out and figuring out what's wrong with my truck.

Welcome from Ellensburg.

I HIGHLY recommend the GM Service/Diagnostic manuals for Fuel/Emissions systems. They are super useful for the TBI engines. You can find them on eBay, look for the R/V-Series ones.
