Re: P0300 troubles
WOW!!! I give this maintenance work a 2 Thumbs up !!!
Its wasnt as easy as I thought but I rate replacing the injectors, on a scale of 1 to 10 ... 10 Being the hardest and requiring advance mechanic knowledge. I rate this a 3 or a 4 ...
But, after replacing the injectors ... I had to reset the factory ecu with my Hypertech programmer. When I started the rig after the install it idle really really rough to the point of dying. I doubt check for leaks and made sure I plug in all the injector plugs. And shut the rig down and reset the factory ecu with the hypertech programmer. And re-started the rig, it runs 10X better idles 10X better. I went for a short little drive and WOW!!! I can definitly feel the difference in acceleration and smoothness of the H2 at speed. The install took me a total of 1hour 30mins. It would have been faster but I had to have a steep learning curve... First Domestic V8 I worked on... I'm use to working on little 4cylinder import motors...
I drove it to work today and cover a total of 80miles. And the Best mpg I was getting a rock solid 13.2mpg ... I totally suggest doing this if your H2 is running alittle rough or past 60,000 miles on the clock...
The only thing I had issues with was trying to replace the spark plugs... I couldnt seem to pull the plug wires to get to them... It was either too late or I was just too tired...
HUMTECH:
Can you help me out on giving me information on how to replace my spark plugs... I want to install these NGK Iriduim spark plugs... Thanx in advance
