So I replaced the Spider injector last weekend because my blazer had this sputtery, lurchy, almost trouble changing gears feeling going on...only below 35 MPH, and usually around 2500 rpms....the check engine light would come off and on, I had the fuel pressure tested and it was ok, had some other things replaces...that didn't help.

Its running amlost perfectly, the lights no longer on....but this morning I felt a slight resistance while excel after stops untill the truck warmed up...maybe its my truck hypocondria acting up?

I want to do several things now....

Replace the cap and rotor
Replace the fuel filter
oil change and filter
air filter change

I want to get a cylinder balance check done as well as fuel pressure

Thinking about replacing the lower intake gasket

Could something be going on with the Throttle???

any tips, tricks, suggestions...you want to slap me....I would love to hear them!

thank you!

and yes I know I should have replaced the gasket while I was in there the first time.

I think my AC compressor is leaking...up top were the lines go in.... ARG!

 

If you can, remove the throttle body and if it a good cleaning. Also get a cleaner for the MAF sensor. To clean it properly, you need to take the MAF sensor apart which is really easy and then blast it with the cleaner. You can use a q-tip as well to clean the sensor, but becarefull not to break it. Actually, I need to clean mine soon.

Sounds like my blazer. I fix on thing and another thing either leaks or breaks.

 

When I took it out to replace the injector it looked really good....I will check again though, thats an easy one......

 

Just open it up and see if its gunked up on the sides.

 

ok...im at work so going to have to wait but will do asap...thank you by the way!
