My blazer has been running really sluggish lately and the other day the engine light came on. The code came up saying it was the egr valve so i decided to clean it out and put a new gasket on as one of the guys posted on how to do it. It was actually running really good and the engine light went off but only ran good for about a day and a half and now is starting to run sluggish again. when you try to accelerate it just seems like it doesnt have all it power and sometimes seems like it just doesnt want to go. I was just reading the last post about the seafoam do you think that could help? Does anyone know what it could be?

Thanks in advance

 

When was the last time the truck got a regular tune up?

Plugs/wires/cap/rotor/fuel and air filters?

 

about 15000km or 10000 miles ago

 

You did get all AC Delco parts, right?

What's the year and mileage of your truck?

Check the oil and make sure your coolant isn't leaking into it...

 

yes i got all ac delco parts its a 95 blazer with 260,000 clicks and i work at an oil change center so i do all my oil changes regularly and theres no noticable coolant leaking in. The last time i changed the oil it did kind of feel a little slippery and wattery than usual but the color was still normal. If coolant was leaking in it would be more milky and wasnt so i dont no.

 

oh and sorry thats 260,000 kms not miles
