Hey guys Im new to this site, I just picked up a 03 Evo a few weeks ago. It ran great all the test drivers I took it, but it was 3 hours away so I only made 2 trips. It ran fine when I was driving it took it out for about 45 min. Only bad thing was a small grind into 3rd. So I got it home and there was a bad oil leak. I guess when he did the timing belt he forgot to put a o-ring back in, so I got that fixed.

I was driving it the other day and did a 2nd and 3rd gear pull, in high RPM it hit fuel cut in 3rd around 5500-6200 but it only does it in 3rd gear and has to be shifting from 2nd to 3rd and on the gas. I saw a few people with the same problem that I had but did not get any answers on what is going on. Any help would be appreciated.

Also the car is almost stock, stock turbo intake and down pipe but cat back is aftermarket and bigger FMIC. The motor looks like it was built at one point since its not common to put a exhaust temperature gauge unless you have a built motor.

Thanks guys.

 

Do you have a boost gauge or a/f gauge? If so what psi is it hitting and what afrs? Im thinking the car needs to be tuned?

 

No I am going to be putting a wideband in next week and a boost gauge in sometime this weekend I hope.

 

Looks good

 

Does it have an aftermarket boost controller? If so you may want to try and turn the boost down for now. You are hitting fuel cut because you are either over boosting, running too lean or the car still has some old tune in it from when it had other parts on it.

 

No thats what i thought that there was one and someone turned it up but i look every where for one and there is nothing.

 

Tune and also check the spark plugs.. I know in these cars the car will run fine until it warms up if the wrong plugs are in..

 

Ok I will look at the plugs they might be wrong cuz in the auto zone book they give the wrong oil filter size so they might have the wrong plugs also

 

might wanna look into if it has a tune on it already(ie: set up for aftermarket parts it no longer has)

 

How many miles does it have?

 

or it has a no lift shift flashed into it...

cb

 

What is an easy way to check to see if it is tuned, I know hondas need obd1 to have a tune but i am not to sure about Evo's. Can you flash a stock ecu?

 

97xxx miles all new maintenance done and everything looks good.

 

If it had WOT shift it would pop when you shifted or hit the clutch but i know I was not on it 100% i didnt it about 2 time making sure it wasnt me.
