Severe hesitation / fuel starvation at 3500rpm
Driving home from work last night, about 3min into my trip I rounded a corner started to come up to speed and the engine just about died on me.
Upon further experimentation I found the engine was hesitating at 3500rpm both off and under load and the idle is slightly rough. I have searched extensively and found many similar threads that present a few solutions (injectors, vac leak, exhaust leak, grounds). Currently I am working on the theory that the secondary injectors are to blame. If you have any suggestions as to a possible cause, I would greatly appreciate hearing them. |
Search 3800 Hesitation.

Definitely not the 3800 hesitation,
I probably did not explain the problem too well. The engine will not rev over 3500 at all; it is not just a little lag kick at 3800. |

Car is going to my mechanic tomorrow, as I don’t have the equipment to diagnose this problem. I will post the resolution once I know for future search purposes. https://www.rx7club.com/attachment.p...1&d=1236605896 |
nice tII. I bet you your relief pressure hose to the valve came loose. easy fix. it goes from under the acv(off the uim) to a air chamber(plastic bulb looking thing). check it before you go spend tons of money on a mechanic. pm if you have question about what im saying. Ive had this problem in the past. in fact I think Iv had every problem and fixed them all. good luck
