Hesitation on accelaration
 
Hey guys, I recently replaced my injectors with Dodge Neon injectors. Ever since I've been getting a hesitation at very low RPM's. ( like 1/4" of gaspedal) Never really bugged to much but when I get this thing up wheeling I dont want it to die on me on the trail. Tooling around my house at the 1/4" throttle it wants to die. Oh ya it's an 89 Renix. Any suggestions?

it may be the map sensor due to the increase of fuel, the map sensor is not adjustable. or check and see if there is a vacuum leak around the the fuel rail.

x2 map sensor and added fuel from injectors....check the injector o-rings for leaks....did you use new o-rings for the injectors and did you rub the o-rings with a dab of oil before inserting the injectors so they don't rip?....see if you have fuel leak/smell around the injectors....check fuel rail pressure....good luck!

Ok, well I did check for any leaks-None. I did dab some oil on the orings before installing them. So it must be map sensor. So I just deal with it?
