new guy with big problems

[frankenstein gt]

i bought an 87 gt air density t top car that uses deep reach plugs? i then bought an 88 gt that was in much better shape with no motor or trans for 400 so this 88 was a maf car i put my motor and ecu in this car the car runs rich surges at idle sputters if you give it more then 1/4 throttle and dies after you give it gas i have replaced the tfi,coolant temp,coil,fuel filter,tps,plugs,idle speed control valve and still runs like complete **** pls forgive my type and grammer i am in the dark

Not positive but I wonder how good the fuel pump is since it was a roller. Maybe check your fuel psi?

 

[frankenstein gt]

The guys I bought the car from put a new pump in it to get it running. Then used the motor for a blower car. So as far ass I know the pump is new. but i have not checked the fuel pressure. and dont have the tools to do so.

37 veiws and one reply nice.

Have you pulled codes?
What mods are done to the car?

 

[frankenstein gt]

msd coil,shorty headers,full 3in to flowmasters with a turndown,k&n filter on stock intake,e fan Thats about it.

I cant pull codes all i have is a testlight and jumper wire and nothing happened

what is the sensor on the driver side next to the first injector looks like a large temp sensor?

 

[HISSIN50]

You need to figure out why you cannot pull codes. That's the place to start.

If the sensor you're talking about is to the driver's side of the dizzy and has one wire on it, it's the temp sender for your gauge.

 

[frankenstein gt]

ok then its the dizzy. i just converted it to mas air and got another mass air ecu.

 

[frankenstein gt]

that did nothing same problem

 

[frankenstein gt]

what about a bad fpr

 

[stykthyn]

all the plug wires in the right area? where is timing set? have you figured out why you cant pull codes? have you gone through the surging idle checklist? It helped me a great deal when I was trying to fix my car.

SD system? Check the readings of the MAP sensor. It could be a bad O2 or exhaust leak as well but I really doubt it. Definatly check the MAP

 

[TenorPlayinGuy]

Sounds like you put the SD Computer into a Mass air car. I don't think that works.....

I know you got another ECU, but what was the code? Ideally you'll want an A9L code. There are others that work.
