problems low rpms
 

Aright just got the car together i went from having a cartech turbo kit on it with a ihi turbo and the manifold was cracked so i changed to a ebay manifold with a evo 16g trubo the car has some sort of engine management on it i unhooked it thinkin it was dumpin to much fuel but then the car wouldnt go into boost the car runs great from 4500 on as soon as its full boost only 9lbs now it did it to when the cartech was on there the guy i bought it off of could never figure out why it did this any ideas on what could cause it to not want to run till 4500

It's painful to read your post. Can you please use a bit of punctuation and a little clearer explanation of things?

what did you unplug? do you have a picture?

research "o2 clamp:

What you need to do is go back to class and learn how to use punctuation and capitalization. Your shit gives me a head ache. I don't know what I just read to be honest.

dammit you beat me.

PEOPLE, USE "AN" IF IT IS BEFORE A VOWEL!

I couldn't stand it so I fixed it, maybe someone can help him out now. my sentences are probably too short. But I needed short sentences. after the one he typed. which took up the whole post. one sentence. one post. wtf.

Sorry about not having clear sentances. I wrote that up real fast before i had to goto work i was hoping it was somthing stupid that was wrong with my car and you guys would know. Only thing i unhooked was o2 sensor but the car did this when i bought it. For a little clear explanation when i goto pull out it just doesnt want to go anywhere it feels like your trying to drive a car with a clogged cat. Ill try to get couple pics of it real quick before i goto work today. I had this same problem on one of my friends 240s he we did a sr20det swap in it and it did the same thing. Found that the crank sensor was bad and thats it ran great after that. If you guys have any idea i would appericiate the help.

I found this when taking pictures. Nice wiring job

Clean up that wiring first. Then I would get a timing gun and make sure the car is timed correctly.

A friend of mine had a problem with his having no power down low. He found out his timing was set at 8*

i had that problem when i still had the afm and before it was warmed up, after it was fully warm it didn't do it. does yours do it all the time?

what injectors are you running? what is your base fuel pressure? is that a stock afm or rx7 afm? how old is your fuel filter? do you have anything controlling timing? what is the timing set to?

yes it does it all the time. I have no idea what injectors that are in it. The guy i bought it off of was a complete idiet and knew nothing. i asked him if it has a diff fuel pump or anything "I dont know im not a mechanic" is what he said i was like wow. no i dont have anything to control timing. Im going to put a light on it prob monday i work non stop this weekend. Where should i set the timing to start with. Also im pretty sure its the stock AFM. Is there a color chart for mazda injectors ill also try to see what size they are to i apperciate you guys tryin to help me

with your setup you're gonna want stock 1.6 injectors which are blue, or the tan 1.8 injectors. without timing control, set base timing to 6* at 850rpm with ten and ground pins jumpered in the diag box. stock fuel pressure with the vacuum line pulled off should be about 50psi, with your afpr try bumping it up to 55. also show us a clear picture of the label on your afm and we'll be able to tell you which it is.

ok ill try to get a pic of that for you on monday if not sooner thanks alot

there isnt any tags on the afpr

.....

Why did you buy the car if the owner was a dumb ass? Who knows what the car has or what its been threw. He did what he wanted ...... to make it your problem.

yea i duno i was hoping it would be a simmple problem then i found the cracked manifold and went downhill from there it was a good deal or wouldnt have bought it

How much did you buy it for? how many miles?

got it for $2000. It has i think 80000 on it.
