about a week ago i replaced my thermostats for my 92 civic dx with a single cam vtec, i drove my car before i replaced it and the vtec worked after the shop replaced the thermostats it doesnt hit vtec anymore its like there was never vtec on my car whats the problem?

 

make sure they didnt steal your ecu

 

or mayb, dey left if unplug????? take it back to dem dude,

 

what do you mean they didnt seal my ecu?

 

How many thermostats did they replace?

You need to get a better seal.

 

He's saying make sure they didnt switch youre ECU with a Nonvtec one.. thats silly. Do you have a CEL?

 

only 1

 

its the same ecu

 

Then jump your ECU and see what code is throwing.
The CEL thread is at the top of the page.

 

thanks im going to try it right now

 

my CEL doesnt pop up at all....

 

are you sure youre connecting the service Jumper correctly? sometimes paper clips are too big. try a small wire, Or just take it to advance auto or autozone and they will scan it for free.

 

thanks for the tips
