hi guys. I've got a little problem with #1 injector. as i recon I've got missfireing on 135 cyl side as i think it is cyl#1 'coz it worked badly before.... So checked sparks, cleaned coils and injectors contacts. Missfire still happened in hot days while ideling.. sometimes. So I guess it's time to change it. i found how to swap it without plenum pull. I just wander what is the best will suit N/A.I cannot find any spec about it. all the info about TT's What will you advice to replace my stock injector? Maybe some one know the place or the pearson where to get it from because i dont trust ebay's refurbished ones.
If the car is missing on cylinders 1,3 and 5 I would think it's an electrical problem not an injector. Check all electrical connectors are firm and clean PTU connectors.
