I was changing the oil friday, and decided to clean the spark plugs & re-gap them. ( Set at .032") They are A/C Delco #63 plugs, and my car runs ritch almost all of the time, so they foul out often. (Bad O2 sensor, I think.) I also advanced the timing about 2deg. to compensate for the fuel additive I've been running. Set like this, I am getting 33mpg, and I can feel a noticeable increase in take off power. HOWEVER, now, when I am driving allong at any speed, when I let of the gas and count slow & steady to 4, Every Single Time the check engine light comes on. Thesplit second I hit the gas, it goes out again. Like I said before, it is running better than ever before. I also disconected the battery last night when I got home and re-connected it when I left for work this morning. (Thinking it might reset the computer thingy) No difference. I do not want to set it back, because I like the way it is running. The dash light is just irritating. Thats all. By the way, Would NGK plugs be ok in the 1.8L engine? I was debating between them or the Bosch Platnum +2 plugs. I just do not like A/C Delco plugs. I might put in Champion plugs. I have allways had great service from them in the past. ( But that has allways been in pickup trucks.) -------------i'll shut up now..........................

 

Bosch suck.. NGK are the best... Denso are in the middle.. but still pretty good

 

yea man, i recomend NGK, Bosch will skrew it up and make it run like ****... well most of the time anyways

 

I have only had ngk's in my 1gens and never had problems. I would use the bosch.

 

I know for a fact they suck

 

Listen to Sebba.... They suck... I work at a pep boys and I know bout those plugs cuz we sell them... and they suck ***

 

I a sry to hear u work at pepboys lol. j/k.

 

Thanks guys. I'll be picking up a set of NGK's tomorrow when I get paid. Is there different types of ngk's or is just the basic ngk plug good enough?

 

get the basic NGK's. Not the other kind.

 

can you clearify this please?? do you use bosch or ngk, cuz you are saying you have had no problem with ngk but yet tell him to get bosch lmao
