bushbasher Posted December 26, 2003 Share Posted December 26, 2003 If you punch it with the spfi it will hesitate for maybe a second and then rev up, it will also hesitate slightly at low rpm under load. The check engine light flashes. However there is a green connector in the engine bay right in the top corner by the strut, which stops the check engine light, but causes the engine to hesitate a bit more severely, and idle a bit lower. Any ideas? Quote Link to comment Share on other sites More sharing options...
MilesFox Posted December 26, 2003 Share Posted December 26, 2003 jims wagon did that, and it turned out to be a bad filament on the MAF you can take the module off the maf body to check it out' you might need dielectric grease(like for ign module) to put it together, not sure Quote Link to comment Share on other sites More sharing options...

mattoh130 Posted December 27, 2003 Share Posted December 27, 2003 MAF body. What, where? Quote Link to comment Share on other sites More sharing options...
jimkup Posted December 29, 2003 Share Posted December 29, 2003 My '88 DL Wagon did the same thing, EA82 SPFI, w/220K miles. I checked the TPS (Throttle Position Sensor) for a dead spot, but nothing major, just a small dropoff in resistance when just starting accealeration. Eventually did a compression check & found #3 cylinder with only about 65psi. All others around 150psi. Replaced both hydraulic lifters on that cylinder & much better now. Also, gas mileage was fluctuating & dropping radically before, but now getting 27 - 30 mpg consistently. Quote Link to comment Share on other sites More sharing options...
