My 94 GT failed the emissions test and so I thought I would be mr. fixit and replace the fuel injectors among other things.
First of all - the injectors are a pain in the axx to get to but when I finally replaced them, I'm not entirely certain I seated them correctly. I put everything back together and started the car and now the engine shakes and hesitates from the get go and doesn't get any better after warm up. I had a perfectly smooth engine and now it acts like the engine is missing a piston. Before I go to the work of getting at these stupid injectors again I wanted to see if it sounds likely that my problem is related. (sounds silly to even ask it, but I really don't look forward to doing this job again).

HC = 1.0237gpm (failed) cutpoint is .9 CO = 8.2135gpm (passed) NOx = 2.5097gpm (failed) cutpoint is 2.1 CO2 = 316.0849gpm -------------------- 94 CelicaGT producing massive amonts of NOx - UGH!!!
