I have a vtec problem. I had a comptech high flow cat for about 2,000 miles now. When I first put on the cat, the vtec engaged fine. But today, I pushed it and the vtec engaged but it stopped. It was hestitating all the way to redline. I could hear the vtec and it was very loud around 5800-6000 rpm but it stopped after that. It took a very long time to get to redline. This was in first gear. It took longer to get to 30-40 than from 0-30. Please help? I checked my oil level and it was fine. It is in the middle. Thanks in advance.

 

test the solenoid

 

Check your spark plugs, wires, distributer cap and rotor.

 

This is not an issue with your comptech cat. Most likely there is an issue residing in the distributor i.e. cap/rotor or the housing itself. As B2finity suggested, check your plugs, wires and dist. One quick easy way to test it is just swap out a distributor with one from another GSR..corresponding year.

1. fill the oil to the top dot.
2. check ignition components, dist. rotor and spark plugs in particular.. - how many miles on these parts?

 

I have about 10,000 miles on the plugs, wire, and distributor. My cat has failed and it rattles a lot and I have not gotten a check engine light. Thanks for the responses.

 

v-tech solenoid.. n maybe short on oil

 

I know where the vtec solenoid is. How do I check if it is functioning correctly? Do I just see if everything is tight and not loose? Thanks.

 

oil change

Yes it is, I am willing to bet the catalyst material broke apart and is blocking exhaust flow when you hit VTEC. It happens all the time with high flow cats.

 

I really hope it is because my cat is really broken right now. It rattles everytime I am idling and no pushing gas while in gear. Thanks for the response.
