Then quit wasting your time and talk to your builder. You PAID them to do the motor, it should be right. I don't understand why people don't go back to the "source"....

 

because im trying to figure out whats wrong...its a LONG drive to my "source" and i NEED my car. im looking for experts who KNOW what could be wrong to help me SAVE a trip/time at the shop if i need to go

 

It could be something as simple as a bad o2 sensor, if there's a problem at all. You should be able to discuss the issue with your builder over the phone and at the least narrow down the troubleshooting list.

As far as helping yourself, have you gone through the troubleshooting section of Section F of the FSM?

 

have you checked your tps?

my FC one would lose about 2-3mpg if it wasn't adjusted correctly.

Did you change your oil at 500miles? Oil changes help a bit.

check air filter?

Cats?

sparkplug wires?

What type of rebuild? Which seals. Used housing take a bit to break in.
Low compression = naughty gas milage

Did you have any porting done?

Were the injectors cleaned?

Basically there is a mess of things that can do this.

call the source and ask or just start digging.

 

The thing is that everyone can 'guess' at the problem but it won't do any good unless someone is actually taking a look at things to eliminate possible problem areas. Just simply asking "what about this" and "what about that" isn't going to get the problem investigated.

Someone is going to have to take a wrench to the car and start testing some things whether it's you or the shop who did the work. As I said earlier, you should take it to the shop so they can't say you caused the problem and end up costing you more money in the end.

 

thankyou mahjik.

 

have you checked your tps?
-no i havent

Did you change your oil at 500miles? Oil changes help a bit.
-oil was changed at 250, 500 and soon to be at 750 (i know, im weird like that)

check air filter?
-filters are almost new

Cats?
-cats are NOT on there as mentioned above

sparkplug wires?
-plug wires are BRAND new NGK's AND new NGK iridium plus (9's)

What type of rebuild? Which seals. Used housing take a bit to break in.
Low compression = naughty gas milage
-motor is a reman not rebuild. was done with 3mm apex seals from Mazda (or so i was told...but ive heard Mazda doesnt do 3mm?!)

Did you have any porting done?
-no porting

Were the injectors cleaned?
-new-ish injectors, but not cleaned

and yea, ill take it to them, but i cant until mid july...thats why im tryin to get things that i can check myself. they cant diagnose a problem w/o acutally seeing it, so i duno

 

Call them on the phone and explain to them what is happening. They might say bring it in or they might tell you what to check. The difference is that if they tell you to do something and it causes a problem, they are still at fault (with the original work). If you go and start tinkering, you might end up releasing them from any more responsibility of the work they have already performed (unless you don't care).

If it were me and I spent money to have all that stuff installed; I'd make damn sure they did their job correctly and completely. They would be getting bugged every darn day until my car acted like it should.

 

yea ive been talking to one of the people online and they dont know unless they see it...they knew it was running really rich before they let it go, so if they dont fix it im going to be pissed
