Brain storm

Hey guys, I have a 1987 camry 5 speed

recently I changed the clutch, works great, after this, the motor was shaking and a motor mount snapped, I ended up changing three motor mounts.
After I had changed the motor mounts the car will not stay idle nor if given some gas it will die quick, so I assume the next best thing, I change the fuel pump,,still nothing : /


Ok rewind,, if i were to start the car and my dad spraying gas into the EFI (air filter) the car will idle fine

we checked efi relay ,,all relays we checked all seems fine,, we unbolted the fuel filter and when we start the car gas poors through, so the fuel pump is fine.
I just dont get it! any help would be appreciated.

side note, it all ran fine until a motor mount snapped and when it did the car was revving up to about 5,000 rpms for about 2 blocks.

If 4 small foil fragments weighing about .2grams each got sucked up into the EFI (intake system) could this be the issue and cause? if so what would i need to change? where would they have ended up?

EDIT: Well i dont think this would be the cause thinking about it because the engine does run if given gas straight from the EGR,,maybe those peaces ended up blocking the fuel line AFTER the fuel pump?

GAHHHHH

EDITEDIT: Today I have spotted more relays under the dash,,I wouldn't be able to conclude how to even test these,,theirs probably 6 of them.

Did you remove the airbox (or just the top of the airbox) when doing the motor mounts? If so, how did you remove the plug on the AFM (air flow meter) on the top of the airbox?

Is the complete intake system put back together?

No sir the airbox was set in stone while changing the mounts, I have 1 sensor for the air box.
lets say if i start the car without the airbox and press the gas it will die because of the sensor not being plugged in, If I just leave it idle it will idle.

but this is not the problem, with the airbox plugged in or not the car will idle at about 1100RPM for a few short moments then die, Now if i had the air box hooked up correctly, started the engine and gave it gas it will shut off even faster. or not start at all. (seems to work better without the airbox?)?

Me and my father did an experiment with spraying gas into where the airbox would suck up air, (not through the hoses) but derectly into the EFI, I turned the car over and it would idle just untill about the moment of him stop spraying gas into the motor,
so i dont understand. we are really puzzled here.

it seems like its getting enough fuel, just not enough air

Please answer my question about how you removed the plug on the AFM... it is very important.

Try putting a jumper between the "B+" and "Fp" terminals in the diagnostics connector under the hood and start the motor again (with the intake system hooked up, etc.). Let us know if this allows the motor to keep running.

thank you so much for the reply's i really appreciate the help but i'm not so good with electrical so this morning i towed it to a trusted mechanic, going to cost a fortune but yea thank you anyways.

EDIT: I will post what the cause of this was.

[shippo]

turns out to be the mass air flow. but what really sucks is i drove it away and 10 blocks later car smelled, engine light comes on..turns out they thought my car was a 91 and its an 87

so i bring it back and well they have to order another one which is on monday it will arrive.

two questions, would a 91 intake (mass air flow) work on an 87? or was it defective?

edit: i found this http://cgi.ebay.com/ebaymotors/87-88...-/310266059950

so im assumeing this was defective

[white90dx]

They should be compatible.

I was hoping to be able to walk you through the steps to check the AFM, but it sounds like you gave up a bit early.

I would suggest getting a used one - new or refurbished ones are quite expensive! (in fact, I might have one in my garage...)

This is very interesting to note because i had a similar issue after replacing the intake tube after working on my car a little while back. My car went to wide open throttle and I couldn't figure out why. I know now that I had a rip in my intake tube and it appears that these air flow meters don't have a real good fail safe built in which allows cars to overrev in similar situations.
