I put fuel injector cleaner in and its still bad. Major power loss all throught rpm and any mph. Its hard to even get up to 40mph, its boggin bad. Sometimes its fine im in first and rev up to 6,800 then second gear it starts out fine then just boggs and car just lags bad. Power loss from fuel somewhere?? I guess I'll check my spark plugs and how much do you think a compression test will be?? This sucks
