spark plugs

put 6 new bosch platinum 2's in my s-10. it hesitates fairly bad when i step on it. the spark plugs i took out were old ac-delco's. they are obviously old and worn when looking at them. i assume they were the original plugs from the manufacturer with 82000 miles on them. i took the bosch out and put the old plugs back in and the hesitation dissappears. WTF!? i was told bosch had a stronger, hotter spark than anything else. makes no sense to me.

seems you're right. i'll probably go with the good old fashioned single pole and gap 'em right. i'm pretty sure gm does all delco from the factory, so i guess i'll buy 6 new delco's. all the hype about quad and double pole plugs seems like wishful thinking.

Somewhere on the Bosch spark plug box it says that if your not satisfied with Bosch spark plugs they will refund your money.

Bosch spark plugs and Chevy dont mix.

well... put the plugs in... and let ur car idle like 10 min. "if it lasts that long"

its the plug is wet.. then you know its rich and if its dry then it would die before 10 min.
