I have a 1988 rx7 fc very that has a few issues.


The car will start up fine when it is cold but it sometimes has a rough idle. Also when I am speeding up once the car hits around 2 -4 rpm it starts to hesitate. Also when the car sits for about an hour or so without being cooled down at all it has a really hard time starting, but it starts fine cold or right after it had been running. If you have any possible things that could be wrong please let me know! I'm stumped and don't know what to do next..

I have done a full fuel injection, service plugs and wires, my iac value is working properly I'm pretty sure, and I have also done a fuel filter.

Please help!!

Thanks

It also has 130,000 original miles and mostly all stock and all original parts

What does this mean, "I have done a full fuel injection."

Dax Novotny

I meant full fuel injection cleaning

Professionally serviced?

Dax Novotny

Yes it was a 3 part injection cleaning kit, I work at a small mechanic shop and we use the kit to clean out the injection system on cars

Does that stuff really work on 25 year old injectors? Probably not.

Dax Novotny

So your saying I might need new injectors?

Not necessarily as sonic cleaning is a better cleaning process and most places will provide a before and after flow chart to show you what improvement if any was made.
