93 MX-3 V6 hesitation issue(edited 7/15/12)
Posted: April 16th, 2012, 10:05 pm
i have a 1993 mx-3 GS v6 5 speed
it has had an engine swap by a previous owner with a K8 from an automatic.
ive cleaned the TB and MAF and replaced the fuel filter.
the engine starts fine. and can be driven pretty normally. until you step on the gas harder then if your driving like a grandma
if i am in 2nd gear at 2000rpm and i punch the gas. All i get is stumble stumble stumble until i let off the gas.
if you learn the gas pedal and EASE into driving you can drive pretty fine. this happens in all gears and all RPM ranges.
(edit)
After taking what you guys have said and figuring out how to get the CEL codes myself here is where we stand.
1long 7 short, 2 long 9 short, 4 long 6 short
17 LHO2S inversion error
29 EGR vent solenoid
46 VRIS #2 solenoid
things i need to know now.
which O2 sensor is that? Front or back?
without knowing what way mazda is looking at the engine. Right half and Left half dont mean squat to me. If anyone knows i would greatly appreciate it!
Ive been playing with the 2 VRIS solenoids on the back of the engine.
the one on the right moves while the engine is cold and i rev the engine up, but stops moving after the engine is warm
If i pull the hose off of it while the engine is running . i hear nothing
The one on the left looks like its .. moving? haha but not in the right direction. it seems to move closed and i start to hear a tick tick tick coming from it until i place my hand on it.
if i pull the hose off of it while the engine is running, you hear air blowing out for a brief moment.
as for the EGR valve. I have not even began with that yet. looks like a new replacement will run at least $170.
Portland has almost no MX-3s in any scrap yards. there is currently one in vancouver,wa and it has basically nothing left
SO. If i must replace the VRIS solenoid. What vehicles are compatable? From what i read i could pull from: MX-6, Millenia, probe, 626?
EGR valve.. any compatable vehicles i could pull from there?
O2 sensors are easily obtainable off of amazon.com. so im not very concerned about that
