Hey Y'all this is my first time to be a member here. I need y'all help and if somebody has an experienced using Lucas 42lbs Fuel Injectors ? I bought OTTP Stage 1 kits and my car is completely bone stock. I put in OTTP stage 1 kits and it come with Lucas Injectors. I change my spark plugs to NGK and gapped it to .035 I started my car and it runs perfect in idle. When I drive my car and I was in 2nd to 3rd gear and 3rd to 4th gear it jumpy like jerk on the way up when I hit the gas alittle more but not all the way. I was concern about that. I checked all vacuum and Fuel Injector seal rings. I wanted to make sure they are sealed. They are sealed and no leak like everything is perfect. But the way the car goes sometimes no jerk if I am lucky but most of the time it just jumpy on the way up like jerk. Is it just because of Lucas 42lbs Injector SUCKS!? I thought about getting New Bosch Green Giant 42lbs Fuel Injector will that help to solve the problems or I have to get GMPerformance 42lbs Fuel Injectors ? Sorry if y'all think my english sucks but bear with me.

 

If you bought it from OTTP I would contact them. I have those same injectors in my car and they work fine.

 

the tune is off

 

Yeah, I found out what cause my car jerk on the way up when I change gears. It's clutch pipe leak. I had to go back to the shop that guy who installed it. I told him he has to fix it again and no charge. I am upset about that but as long he is gonna fix it then I am good. Let's hope he fix it right with clutch pipe. I know it's tricky.

 

Those Injectors are Good, I have them and they worked Great, But now their just sittin around cause I now have #60 Injectors.
