Hi I have a 89' RX7 Convertible with an automatic tranny. I rebuilt the motor last winter and ran great until recently this problem arose. For some reason after about 10 to 15 minutes after the car has been started the check engine light comes on and the RPM's bog down really low, its very hard to accelerate you have to just barely push on the gas, if you floor it it almost dies, but it does idle the same though. To fix the problem temporarily I turn off the car and restart it, after I do that it works great again but the same symptoms occur after another 10 to 15 minutes. I have replaced the O2 sensor, Coils with no luck (even though I figured it wouldnt help anyways)... any advice or comments would be appreciated thank you.

 

You have a bad OMP. Buy another. It's a common problem on series five. Some refer to it as the LIMP mode, when the OMP goes bad. Let us know how much you paid for a new one. humor.

 

Thanks I'll try it out

 

Sorry to bother you guys again but what does an OMP stand for again?

 

check the FAQ. Oil Metering Pump. Metering Oil Pump.

 

I thought so... thanks for the quick reply iceblue I appreciate it alot

 

that sounds like what mine was doing, it was a clogged cat, might want to check it ou

 

check engine codes before buying anything or spending any money

 

Just wanted to let you guys know that I fixed it, it was the omp, fortunately I have another 89 convertible that I use as a parts car so it was free Thanks for all your help espically Hailers, hail to you my friend! By the way isnt the car in my avatar yours? I also have a 87 turbo needs a rebuild for the 7th time sadly though, but I can do it pretty quickly now so its all good. Thanks again everyone.
