HELP please engine bugging out
 

Hey guys what's up I got a question here, I just started premix my gas with tcw3 and it ran smooth but then, now every time I pass 4rpms it like stalls alittle and bugs out, like if it didn't want to pass 4rpms. Please explain what's going up!

3800 rpm is when the secondary injectors kick on so you might have an issue w/that aspect. Usually, it is related to a poor engine ground. If you can gently pass through this level but it bogs when you punch it then it reinforces the notion that you have a secondary injector issue.

Which brand of injectors you guys recommend?

Your injectors themselves could be fine but the grounding issue would make them not operate as they should. Just check,improve your main engine ground. Very easy to do.

Or injector clip problem, seen it happen more than once. Worth checking it out.

Im having a similar issue with my car too. I was driving yesterday in traffic for like 50 min bumper to bumper. After traffic cleared when i would give my car gas it would start bugging out. I pulled over and turned the car off for like 5 mins. Then i got back in it and it drove normal again.
