After driving maybe 10 miles I have no acceleration or more than an idle. Car will restart if turned off but no more than an idle. It’s as if something under the hood doesn’t work after heating up. The coolant is not hot just normal. After cooling off under the hood works just fine until driven …

You’re right, ignition issues would probably cause different problems. Does this have a carb? Has it been rebuilt?

[image] VerlinSchock: but if [the ignition system] were failing wouldn’t it be intermittent and the engine would miss. Idles perfectly just no acceleration. If the timing advance vs engine rpm wasn’t working something like this might be a symptom. Probably not the first thing to check, but s…

You may need a helper to see if the throttle is moving when the engine is warm. It may be stuck at that time and your throttle cable may be sloppy or not held in place somewhere. A small clamp may be broken and the cable might just shift around and not pull hard enough. This is a strange problem for…

I guess it’s a carb but the fuel input is something called throttle-body injection. Not rebuilt.

Actually was a first consideration but it doesn’t have points or the usual vacuum I’m familiar with. Not sure how it works. But I should be able to check that when the problem occurs and see what happens when I try to increase the rpm. You’ve given me something to check. Thanks.

Hello, it is a small E-16i fuel injected engine, mine had a TBI fuel injector, next question, do you have access to tools and a manual on your car ? The Pulsar has a single ox sensor at front and your ecm is located under the passenger seat. I had a pulsar NX back in the 90’s and it was a nice car, …

[image] VerlinSchock: I guess it’s a carb but the fuel input is something called throttle-body injection. “throttle body injection” means the engine is fuel injected , not a carb. There’s two common different types of configurations for fuel injection, throttle body and port. Port injecti…

I haven’t gotten back to trying things with the car. I’m kind of hoping for an exhaust restriction. One of the other guys mentioned an oxygen sensor which I didn’t realize I even had. Sure enough it’s in the user manual. Thanks for the additional information.

Suggest you find a copy of Popular-mechanics-complete-car-care-manual . It’s a good introduction to how electronic fuel injected cars work, and will explain in a clear way most of questions you are having. Most public libraries and larger bookstores have it.

This is not a Nissan NX. There was not an entry tor a Pulsar NX. The engine is a little 4 that’s also in the Sentra, single cam.
