1987 Chevrolet Camaro - Answered Questions & Fixed issues
My Iroc is an 88, 305 TPI. Starts fine. Idles
Inspecting your other problems first:(as yo replaced you MAF)
Take a real good look at the throttle "butterfly" valve. They have a
tendency to get buildup with dirt and will stick slightly open,
confusing the computer into thinking that you are pushing on the "go"
pedal. Get some carb cleaner, or even better, GM Top Engine cleaner,
and really clean out the throttle valve and air intake area. I have
seen several similar problems fixed this way. If this does not take
care of it, it may be worth paying someone an hours labor to hook up a
good scanner and see what is going on. You can waste a lot of money on
the newer cars throwing a lot of expensive parts at them and still not
fixing the problem. It could be a simple loose connection somewhere. A
good tech can catch this type of stuff with a good scan tool.
Always check the fuel pressure .
It might be the in tank fuel pump or clogged filter
checking that can be done by you easily:
you might check the ground wires that are located at various places on the engine
check your IAC valve (idle air control), this is located on the
passenger side underneath the throttle body. These get all carboned up
and can't re-seat themselves properly. You may have to perform a
minimum idle setting also. This isn't to hard but is more complicated
than on a non-computer controlled
MAF signal checking:
I used a small straigt pin and shoved it in the back side of the MAF
connector on the signal line. I started the motor and expected to see
the voltage signal to start low at idle and increase smoothly with
engine speed. Instead what I saw was a stead 5 volts meaning the ECU
had supplied the bias signal but the MAF wasn't loading it down to
generate the signal. The issue was that the MAF socket pins in the
connector were slightly sprung and had a thin layer of oxidation on
them. I tiny rolled up piece of sand paper buffed the terminals up. A
tiny pick probe was used to squeeze the socket pins closed slightly. A
light doping of dielectric grease kept the moisture out and it's been
running fine for 5 or so years no
Hope this helps,kindly RATE ME
87 camaro cleand maf now wont turn over at all
There is probably something else going on - a malfunctioning MAF should not immobilize the engine, but trying to clean it is a bad idea as it is very sensitive to failure with the wrong cleaning procedure. Check the power at the starting motor solenoid with the ignition in start position - if missing, check fuses, and wiring back to the ignition switch, and the switch itself.

Most likely the IAC (idle air control) motor is sticking and dirty. Clean the throttle body, make certain the accelerator cable and TV cable is adjusted properly. Good luck
1987 cheverolet camaro will not start. Replaced a
I think I would be looking at the crank angle sensor and/or the cam sensors on this vehicle.It seems to me the engine isn't getting the signal to fire up.What happens when you squirt some fuel into the combustion chamber ? If it fires up I would be looking at cleaning the injectors.If it doesn't fire up What's the pressure on the fuel rail. does it have a buy pass pressure valve on the rail.Some suggestions good luck
How to reset ecu
remove ground cable to battery for five min to one hour then reconnet if still on after another problem most likely
Engine cold start problems
Is there a check engine light on and if so have you had the codes checked?
There is an idle air control motor located on the side of the throttle body. It has a 4 wire square plug connecting to the motor. It is likely not controlling the idle air. It may be varnished and stuck or has failed. You can remove it, clean it and retry it or replace the motor.
Good luck.
How do I reset check engine light in 1987 camaro
Old problem, but if not done already, disconnect neg terminal of battery momentarily, then reconnect and start. The ECM with go thru a re-learn for several minutes. The codes will reset, but if the problem still exists, the code will be re-thrown. Good luck.
