Phishnoob Posted March 23, 2014 Share Posted March 23, 2014 My fiance's Loyale was not running at135K miles, and did a lot to it. Specifically for running, the idle air valve and throttle body were replaced. I jumpered out the EGR valves with straight vacuum tubing and installed 10W 33 ohm resistors to clear the check engine light. Rebuilt the entire throttle body with a kit from Rock Auto. Cap, rotor, plugs and wires all replaced with high quality parts, and running NGK copper plugs. The car idles well, but still seems to be a little rich under accelleration. When the engine is still warming on our cold mornings, there is a dead spot at 45 mph and the car doesn't want to go faster. The car feels too fat all the time, and not really running at the right ratio. Any ideas? Quote Link to comment Share on other sites More sharing options...

Phishnoob Posted March 23, 2014 Author Share Posted March 23, 2014 When was the last time the fuel filter was replaced? Last year. I can check fuel pressure if necessary. Quote Link to comment Share on other sites More sharing options...

bratdad Posted March 25, 2014 Share Posted March 25, 2014 Could be a weak fuel pump! Quote Link to comment Share on other sites More sharing options...
Phishnoob Posted March 25, 2014 Author Share Posted March 25, 2014 Could be a weak fuel pump! I work at a place that is 4 10's (which as a manager is really 4 12's) so this will have to wait until Friday. I'll check fuel pressure and report back. The filter is pretty new, but the rest is 20 year old original. An airtex fuel pump is 138 at Rock Auto, and other brands are a hundred bucks more. Thanks for the inputs!

bratdad Posted March 27, 2014 Share Posted March 27, 2014 I've had good luck getting suby parts thru Partsgeek.com where others don't offer them. Might be worth checking. I can't remember where I got the fuel pump tho! Quote Link to comment Share on other sites More sharing options...
